With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.2933-29-1,2-Amino-4,5,6,7-tetrahydrobenzothiazole,as a common compound, the synthetic route is as follows.
General procedure: The solution of (15) (1 mmol) in anhydrous dichloromethane (10 mL) was supplemented with the appropriate isocyanate or isothiocyanate (1.1 mmol) and refluxed for 5 h. The solid product was washed with water and purified by re-crystallizationfrom aqueous ethanol, and air-dried to give the corresponding urea or thiourea compounds (16a-h). 5.3.2.2.2 1-isopropyl-3-(4,5,6,7-tetrahydro-1,3-benzothiazol-2-yl)urea (16b) 60% yield; mp = 92-94 C. IR (KBr) (numax/cm-1): 3294, 3070, 2927, 1679, 1569, 1234. 1H NMR (DMSO) (delta/ppm): 1.09 (d, J = 6.6 Hz, 6H, (CH3)2), 1.73 (br s, 4H, CH2), 2.47 (br s, 2H, CH2), 2.56 (br s, 2H, CH2), 3.75 (m, 1H, CH), 6.41 (d, J = 7.3 Hz, 1H, NH), 9.83 (br s, 1H, NH). 13C NMR (DMSO) (delta/ppm): (CH3): 22.76; (CH2): 22.04, 22.63, 22.98, 25.94; (CH): 41.23; (Cq): 141.45, 142.74, 151.97, 167.83. Anal. (C11H17N3OS) theoretical: 55.20% C, 7.16% H, 17.56% N, 13.39% S; found: 55.55% C, 7.21% H, 17.30% N, 12.99% S.
2933-29-1, 2933-29-1 2-Amino-4,5,6,7-tetrahydrobenzothiazole 18046, athiazole compound, is more and more widely used in various fields.
