Procedure

A mixture of 8-(3-amino-2,6-dichlorobenzyloxy)-3-bromo-2-methylimidazo[1,2-a]pyridine dihydrochloride (100 mg) and acetic anhydride (100 mg) in dry pyridine (2 ml) was stirred at 90° C. for one hour. The cooled mixture was poured into an ice water (10 ml). The precipitated solid was collected, washed with water, and dried under reduced pressure to give 8-(3-acetylamino-2,6-dichlorobenzyloxy)-3-bromo-2-methylimidazo[1,2-a]pyridine (65 mg) as a solid.
