Reaction Steps
Ethyl 7-chloroimidazo[2,1-b]-benzthiazole-2-carboxylate was prepared according to the procedure as outlined in Example 1, (Step 1). Starting from 6-chloro-2-amino benzothiazole (9.2 g, 50 mmol) and ethyl bromopyruvate (11.6 g, 60 mmol), 8.5 g (60% Yield) of ethyl 7-chloroimidazo[2,1-b]-benzthiazole-2-carboxylate was isolated as brown solid. (M+H) 281.
