Procedure

2-Formyl-5-methylimidazo[2,1-b]-benzthiazole was prepared according to the procedure outlined in Example 1, (Step 3). Starting from 5-methyl imidazo[2,1-b]-benzthiazole-2-methanol (2.0 g 9.1 mmol) in methylene chloride/DMF(300 mL: 50 mL) and active MnO2 (12 g, excess), 700 mg (35% Yield) of the aldehyde derivative was isolated as brown solid. (M+H) 217.
