A mixture of 4-chloro-N-((6-chloro-2-phenylimidazo[1,2-a]pyridin-3-yl)methyl)pyrimidin-2-amine (50 mg, 0.135 mmol) and 4-methylpiperidin-4-ol (200 mg, 1.74 mmol) in t-BuOH (0.5 ml) was heated 95° C. until the reaction was completed. The mixture was diluted with ethyl acetate and the resulting mixture was washed with saturated NaHCO3 and brine, dried over Na2SO4 and concentrated by evaporation. The crude product was purified by silica gel chromatography (methanol/methylene chloride gradient) to title compound.
