摘要：

Thiazole 1, when reacted with chloroacetyl chloride, afforded N-(5-acetyl-4-methylthiazol-2-yl) chloroacetamide 2. It has been found that compound 2 reacted with alpha-cyanocinnamonitrile derivatives 6a-c to afford reaction products 8a-c. Also, compound 2 coupled smoothly with benzenediazonium chloride afforded the phenylhydrazone 14. Coupling of the sulfonium bromide 17 with diazotized aromatic amines or N-nitrosoacetanilides afforded the arylhydrazones 20a,b. Treatment of 16 with 2-cyanoethanethioamide afforded [4-(2-amino-4-methylfhiazol-5-yl) thiazol-2-yl] acetonitrile 22. (C) 2000 John Wiley & Sons, Inc.
