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 (130.4 mg, 0.219 mmol) and cyclopropylamine (2.0 mL) was stirred at 60° C. for 25.5 hrs. The reaction mixture was concentrated in vacuo. The residue was purified by silica gel column chromatography eluting with a 10-60% 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 (45.6 mg, 0.909 mmol, 42%).
