Procedure

To a solution of ethyl 3-({6-[(5-methyl-2-phenyl-1,3-oxazol-4-yl)methoxy]-3-phenyl-1-benzofuran-2-yl}methoxy)-1-phenyl-1H-pyrazole-4-carboxylate (0.60 g) in tetrahydrofuran (10 mL) was added lithium aluminum hydride (0.055 g) at 0° C., and the mixture was stirred at 0° C. for 1 hr. Sodium sulfate decahydrate (0.46 g) was added to the reaction mixture, and the mixture was stirred at room temperature for 30 min. The reaction mixture was diluted with ethyl acetate and the precipitate was filtered off. The filtrate was concentrated to give [3-({6-[(5-methyl-2-phenyl-1,3-oxazol-4-yl)methoxy]-3-phenyl-1-benzofuran-2-yl}methoxy)-1-phenyl-1H-pyrazol-4-yl]methanol as colorless crystals (0.45 g, yield 80%). Recrystallization from ethyl acetate-hexane gave colorless prism crystals. melting point: 118-119° C.
