실험 절차

Ethyl 5-methylimidazo[2,1-b]-benzthiazole-2-carboxylate was prepared according to the procedure as outlined in Example 1, (Step 1). Starting from 4-methly-2-amino benzothiazole (8.0 g, 48.7 m.mol) and ethyl bromopyruvate (14.0 g, 71.7 mmol), 6.0 g (45% Yield) of ethyl 5-methylimidazo[2,1-b]-benzthiazole-2-carboxylate was isolated as a brown solid. (M+H) 261.
