To a suspension of 4-(((5-chloro-2-thienyl)methyl)amino)-1-(2-cyclopropyl-3-methylimidazo[1,2-a]pyridin-6-yl)pyridin-2(1H)-one (11.5 mg) in DMF (1 ml) was added NaH (60% in oil, 1.7 mg) at 0° C. After the reaction mixture was stirred at 0° C. for 10 min, iodomethane (2.61 μl) was added to the reaction mixture. The mixture was stirred at room temperature for 3 h. The mixture was quenched with water, and extracted with EtOAc. The organic layer was separated, washed with water and brine successively, dried over MgSO4 and concentrated in vacuo. The residue was triturated with IPE, and the resulting solid was collected by filtration and washed with EtOAc-IPE to give the title compound (4.0 mg) as a pale yellow solid.
