Participants

Reaction Steps

To a solution of 5-{9-chloro-6-[1-(difluoromethoxy)-2,2,2-trifluoroethyl]-3,4-dihydropyrimido[1,2-a]benzimidazol-1(2H)-yl}-6-methylpyridin-2-ol (30.0 mg, 0.0648 mmol) in toluene (1.0 mL) was added silver carbonate (35.7 mg, 0.130 mmol) and 2-iodopropane (32.3 μL, 0.324 mmol). The reaction mixture was stirred at room temperature for 5 hrs. The starting material wasn't consumed completely. The mixture was stirred at 50° C. for 5 hrs. After cooling the mixture was filtered through on the pad of celite. The filtrate was concentrated. The residue was purified by silica gel column chromatography eluting with a 0-30% ethyl acetate/n-hexane gradient mixture to give the title compound as a colorless amorphous (29.3 mg, 0.0633 mmol, 98%).
