Reaction Steps

1-(2,5-Difluorophenyl)ethanone (3.00 g) and 1H-triazole (1.99 g) were dissolved in N-methylpyrrolidone (5 ml). To the solution, potassium carbonate (2.66 g) was added, and the mixture was stirred at 140° C. for 4.5 hours. After standing to cool, water and ethyl acetate were added to the reaction solution to separate the aqueous and organic layers. The aqueous layer was subjected to extraction with ethyl acetate. The organic layers were combined, washed three times with saturated saline, dried over anhydrous sodium sulfate and then concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (n-hexane-ethyl acetate) to obtain the title compound (1.05 g).
