Reaction Steps
A mixture of 5-{9-chloro-6-[1-(difluoromethoxy)-2,2,2-trifluoroethyl]-3,4-dihydropyrimido[1,2-a]benzimidazol-1(2H)-yl}-6-methylpyridin-2-yl trifluoromethanesulfonate (122.3 mg, 0.206 mmol) and dimethylamine (2.0 M tetrahydrofuran solution, 1.0 mL) was stirred at 70° C. for 24 hrs. The reaction mixture was concentrated in vacuo. The residue was purified by silica gel column chromatography eluting with a 0-40% ethyl acetate/n-hexane gradient mixture. The resulting solid was recrystallized from ethyl acetate/n-hexane to give a title compound as a colorless powder (67.3 mg, 0.137 mmol, 67%).
