Reaction Steps

(4-[(Cyclopropylamino)carbonyl]-1-{4-[(ethylamino)carbonyl]phenyl}-1H-1,2,3-triazol-5-yl)methyl methanesulfonate (204 mg, 0.5 mmol) obtained in Example 126a), potassium carbonate (69 mg, 0.5 mmol, 1.0 eq.) and 2,2-difluoroethanol (0.5 ml) were suspended in acetonitrile (3 ml), and the suspension was stirred at room temperature for 12 hr. The reaction mixture was diluted with ethyl acetate (30 ml), washed with saturated aqueous sodium hydrogen carbonate solution and saturated brine, dried over anhydrous sodium sulfate, and concentrated. Diethyl ether was added and the precipitate was collected by filtration, washed with diethyl ether and dried to give the title compound as a white powder (160 mg, 83%).
