The novel and versatile cyanomethyl 2amino-4-methylthiazolyl ketone (5) was prepared by treatment of bromomethyl 2-amino-4-methyl thiazolyl ketone (4) with potassium cyanide. Reaction of 5 with heterocyclic diazonium salts 6a,b and 10 afforded the corresponding hydrazones 7a,b and 11, respectively.
