In an article, published in an article, once mentioned the application of 1603-91-4, Name is 4-Methylthiazol-2-amine,molecular formula is C4H6N2S, is a conventional compound. this article was the specific content is as follows.SDS of cas: 1603-91-4

Reaction of [Ln(CH2SiMe3)3(thf) 2] (Ln = Y, Yb, and Lu) with one equivalent of Me 2Si(C5Me4H)NHR? (R? = Ph, 2,4,6-Me3C6H2) affords straightforwardly the corresponding half-sandwich rare-earth metal alkyl complexes [{Me 2Si(C5Me4)(NR?)}Ln(CH 2SiMe3)(thf)u] (1: Ln = Y, R? = Ph. n = 2: 2: Ln = Y, R? = C6H2Me32,4,6, n = 1; 3: Ln = Y, R? = tBu, n = 1: 4: Ln = Yb. R? = Ph, n = 2: 5: Ln = Lu, R? = Ph, n = 2) in high yields. These complexes, especially the yttrium complexes 1-3. serve as excellent catalyst precursors for the catalytic addition of various primary and secondary amines to carbodiimides, efficiently yielding a scries of guanidinc derivatives with a wide range of substituents on the nitrogen atoms. Functional groups such as C?N, C?CH. and aromatic C-X (X: F, Cl, Br, I) bonds can survive the catalytic reaction conditions. A primary amino group can be distinguished from a secondary one by the catalyst system, and therefore, the reaction of 1,2,3,4-tetrahydro-5-aminoisoquinoline with iPrN=C=NiPr can be achieved stepwise first at the primary amino group to selectively give the monoguanidine 38, and then at the cyclic secondary amino unit to give the biguanidine 39. Some key reaction intermediates or true catalyst species, such as the amido complexes [{Me2Si(C 5Me4)(NPh)}Y(NEt2)(thf)2] (40) and [{Me2Si(C5Me4)(NPh))Y(NHC6H 4Br4)(thf)2] (42), and the guanidinate complexes [{Me 2Si(C5Me4)(NPh)}Y{iPrNC(NEt2)(NiPr)) (thf)] (41) and [{Me2Si(C5Me4)(NPh)}Y(iPrN) C(NC6H4Br-4)(NHiPr))(thf)] (44) have been isolated and structurally characterized. Reactivity studies on these complexes suggest that the present catalytic formation of a guanidine compound proceeds mechanistically through nucleophilic addition of an amido species, formed hy acid-base reaction between a rareearth metal alkyl bond and an amine N-H bond, to a carbodiimide, followed by amine protonolysis of the resultant guanidinate species.

Application of 1603-91-4, An article , which mentions 1603-91-4, molecular formula is C4H6N2S. The compound – 4-Methylthiazol-2-amine played an important role in people’s production and life.

The salts formed from alpha-aminothiazoles and alpha-bromo ketones (RCOCH2Br) have been basified, and the products converted into amides. Examination of the amides established that they are 2-acylimino-2,3- dihydrothiazoles rather than 2-acylaminothiazoles. Thus the alpha-bromo ketones attack the endo-N of the 2-aminothiazoles, and the imidazo[2,1-b] thiazoles obtained by cyclising the salts have the substituent (R) of the bromo ketone at position 6. Efficient procedures have been developed for preparing a range of imidazo[2,1-b]thiazoles. Related reactions of 2-aminothiazoles, with an alpha-bromo aldehyde and with ethyl bromoacetate, have been studied.

A document type is Article, introducing its new discovery., Application In Synthesis of 4-Methylthiazol-2-amine

Reinvestigation of the alkylation of 3-phenyl-5,6-dihydroimidazolo<2,1-b>thiazole has shown that methylation occurs exclusively at the 7-position, and that the free base is readily solvolysed to a mixture of 1-methylimidazolidin-2-one, 1-methylimidazolidine-2-thione, and diphenacyl sulphide and disulphide. 3-Methyl-5,6-dihydroimidazolo<2,1-b>thiazole with methane- and arene-sulphonyl chlorides gave the corresponding 7-sulphonylthiazolium chlorides.On heating, these rearranged to 3-(2-chloroethyl)-4-methyl-3-aryl (or alkyl)sulphonylimido-2,3-dihydrothiazoles.The 7-(4-chlorophenylsulphonyl) derivative lost this substituent with aqueous base while concentrated aqueous ammonia attacked the 7a-position leading to a 3-<2-(p-chlorobenzenesulphonamido)ethyl>-2-imino-4-methyl-2,3-dihydrothiazole.

Human nasopharyngeal carcinoma is a common head and neck malignancy with high incidence in Southeast Asia and Southern China. It is necessary to develop safe, effective and inexpensive anticancer agents to improve the therapeutics of patients with nasopharyngeal carcinoma. A series of small molecular compounds based on 6-(pyrimidin-4-yl)-1H-indazole were synthesized and evaluated for antiproliferative activities against human nasopharyngeal carcinoma cell lines SUNE1. Compounds 6b, 6c, 6e and 6l showed potent antiproliferative activities similar to positive control drug cisplatin in vitro with lower nephrotoxicity than it. N-[4-(1H-Indazol-6-yl)pyrimidin-2-yl]benzene-1,3-diamine (6l) was selected for further study. It was found that 6l induced mitochondria-mediated apoptosis and G2/M phase arrest in SUNE1 cells. Furthermore, compound 6l at 10 mg/kg can suppress the growth of an implanted SUNE1 xenograft with a TGI% (tumor growth inhibition) value of 50 % and did not cause serious side effects in BALB/c nude mice. This study suggests that 6-(pyrimidin-4-yl)-1H-indazole derivatives are a series of small molecule compounds with anti-nasopharyngeal carcinoma activities.
