Reaction Steps

To a suspension of sodium hydride (60% dispersion in mineral oil, 0.844 g) in N,N-dimethylfounamide (30.0 mL), 2,2,2-trifluoroethanol (2.11 g) was added at 0° C. and thereafter the mixture was stirred at room temperature for 30 minutes. To the reaction mixture, a solution of 3,4-difluorobenzaldehyde (2.00 g) in N,N-dimethylformamide (10.0 mL) was added and thereafter the mixture was stirred at room temperature for 30 minutes. After adding 1 mol/L hydrochloric acid at 0° C., three extractions were conducted with ethyl acetate. The combined organic layers were passed through a phase separator and thereafter concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=80:20-30:70) to give the titled compound as a colorless oil (2.50 g).
