Simple exploration of 90533-23-6

The synthetic route of 90533-23-6 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.90533-23-6,4-(3-Chlorophenyl)thiazol-2-amine,as a common compound, the synthetic route is as follows.

General procedure: (iv) 10a-10n (2 mmol, 1.0 equiv.) wasdissolved in dry dichloromethane (10 mL), and the reaction was followed to add 5-nitro-2-furoicacid (2.4 mmol, 1.2 equiv.), DMAP (2.4 mmol, 1.2 equiv.), EDCI (4 mmol, 2.0 equiv.),then stirred under room temperature for 1 day. The reaction mixture wasquenched with H2O (10 mL) and extracted with dichloromethane (2*30 mL).The combined organic layers were washed in turn with 2N HCl (20 mL), H2O(20 mL) and brine (20 mL). The organic layer was collected, dried overanhydrous Na2SO4 and concentrated in vacuo. The residue waspurified by column chromatography on silica gel (hexane/EtOAc=8:1 to 4:1) toprovide 12a-12n. 11a and 11b were prepared by thesame way, just starting from 10b and replacing 5-nitro- furic with2-furoic acid and 4-nitrobenzoic acid. The yield was 29~80%., 90533-23-6

90533-23-6,90533-23-6, 4-(3-Chlorophenyl)thiazol-2-amine is a thiazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

General procedure: Iodine(18.80 g, 74.1 mmol) was added to 1-(2,5-dichlorophenyl)ethanone (10.67 ml,74.1 mmol) and thiourea (11.27 g, 148.0mmol). Thereaction mixture was stirred and heatedto 100 C overnight. After cooling to room temperature, the reaction mixture was triturated with diethylether (about 50 mL) to remove any unreacted iodine and1-(2,5-dichlorophenyl)ethanone. Thesolid residue was put in cold distilled water (100 mL) and treated withammonium solution to pH 9-10. The precipitated thiazole was collected togive 4-(2,5-dichlorophenyl)-1,3-thiazol-2-amine (11.2 g, 62%yield) as a yellow solid. MS(ES+) m/z 245.0, 247.0 (MH+).A solution of[4-(ethylsulfonyl)phenyl]acetic acid (0.239 g, 1.1 mmol), 4-(2,5-dichlorophenyl)-1,3-thiazol-2-amine(0.245 g, 1.0 mmol), EDC (0.230 g, 1.2 mmol) and HOBt (0.184 g, 1.2 mmol) in dichloromethane(DCM) (10 mL) was stirred at room temperature overnight. The mixture was pouredinto water, and extracted with DCM. The organic phase was washed with water andbrine, dried over anhydrous sodium sulfate, filtered and concentrated under reducedpressure to give the crude product. The crude was purified by mass directedautopreparation (MDAP) to afford N-[4-(2,5-dichlorophenyl)-1,3-thiazol-2-yl]-2-[4-(ethylsulfonyl)phenyl]acetamide(6a) (177 mg, 37% yield) as a white solid.
