Hydroxymethylation of 2-aminothiazol derivatives at 5 position irritated by microwave was reported. The reaction results were compared by the method of microwave, sealed tube and reduction from ester. A series of novel hydroxymethyl derivatives were obtained. Through the experiments, sealed tube condition demanded high thermal stability of the substrate, and the reaction yield was low with messy reaction solution and long reaction time. The yield of reduction from ester is poor with longer synthetic route. The hydroxymethylation under microwave irradiation gave high yields with short reaction times. 2-Cyanoacetate sodium salt was prepared from NaH, and the yield was improved. Novel derivatives of aminomethylation on 5 position are obtained after cyclization and reduction.

Key words: 2-aminothiazole, microwave reaction, thiazole
