Procedure

To a solution of 1H-imidazo[1,2-b]pyrazole (2.5 g) in tetrahydrofuran (10 ml) was added acetic anhydride (3.1 ml) under stirring at 35° C. and the mixture was stirred for 2 hours at the same temperature. The reaction mixture was evaporated in vacuo to give 1-acetyl-1H-imidazo[1,2-b]-pyrazole (2.7 g).
