3-Aryl-2-chloropropanals 2a-h have been prepared by the reaction of arenediazonium chlorides 1a-h with acrolein in the conditions of Meerwein arylation (water-acetone, CuCl2 as a catalyst). These aldehydes react with thiourea by refluxing in ethanol to obtain 2-amino-5-R-benzyl-1,3-thiazoles 3a-h (R = 2-Cl, 3-Cl, 4-Cl, 3-CF3, 2,4-Cl2, 2,5-Cl2, 3,4-Cl2, 3-Cl-4-Me) with high yields. The resulting 2-aminothiazoles were acylated with chloroacetic acid chlorides to form 2-chloro-N-(5-aryl-1,3-thiazol-2-yl)acetamides 4a-h with the yields of 68-91%. By the reaction of compounds 4a-h with 4-amino-5-methyl-4H-1,2,4-triazole-3-thiole 5 a series of novel 2-(4-amino-5-methyl-4H-[1,2,4]triazol-3-ylsulfanyl)-N-(5-R-benzylthiazol-2-yl)-acetamides 6a-h (71...
