Reaction Steps
A solution of 1-[3-(3,5-difluorophenyl)-5-methylimidazo[1,2-a]pyridin-2-yl]ethanone (0.23 g, 0.82 mmol) in methanol (9.5 mL) was treated with ammonium acetate (0.63 g, 8.2 mmol) and heated at 65° C. for 1 h. The reaction mixture was treated with sodium cyanoborohydride (0.15 g, 2.5 mmol) and heated at 65° C. for 4 h. The reaction mixture was concentrated and purified by preparative LCMS to give the desired product (0.13 g, 56%) as a colorless oil. LCMS for C16H16F2N3 (M+H)+: m/z=288.1.
