To a stirred solution of 7-methoxy-2-methylimidazo[1,2-α]pyridine-3-carboxylic acid (1.2 g, 5.82 mmol) in DMF (25 ml) was added EDCl (1.23 g, 6.41 mmol), HOBt (0.87 g, 6.41 mmol), N-methyl morpholine (767 ul, 11.64 mmol), methylamine (2M in THF, 6 ml, 11.64 mmol) and DMAP (70 mg, 0.58 mmol) sequentially, and the resulting mixture stirred at ambient temperature for 16 hours. The resulting solution was concentrated in-vacuo and pre-absorbed onto SiO2 and then purified by flash chromatography (eluting with 5-8% MeOH/DCM) to yield 7-Methoxy-N,2-dimethylimidazo[1,2-α]pyridine-3-carboxamide, 1.11 g, 87%, as a white solid.
