Procedure

Sodium hydroxide (1.0 M aqueous solution, 0.16 mL, 0.16 mmol) is added to a solution of 7-(4-bromo-2-chlorophenylamino)-3-[(tert-butoxycarbonylmethylamino)-methyl]-8-chloroimidazo[1,2-a]pyridine-6-carboxylic acid methyl ester (60) (15 mg, 0.026 mmol) in 4:1 MeOH/water (5 mL). When the reaction was complete, the solution was diluted with water, acidified to pH 3 by addition of 1.0 M aqueous HCl, and extracted with ethyl acetate. The organic extracts were dried over NaSO4, filtered, concentrated in vacuo to provide the desired product as a white crystalline solid (12 mg, 84%). MS (APCI−) m/z 541, 543, 545 (M−; Cl, Br pattern) detected.
