Participants

Reaction Steps

To a solution of ethyl 3-[(4-{[2-(2-furyl)-5-methyl-1,3-oxazol-4-yl]methoxy}-3-methoxybenzyl)oxy]-1-(pyridin-3-ylmethyl)-1H-pyrazole-4-carboxylate (0.71 g) in tetrahydrofuran (30 mL) was added lithium aluminum hydride (0.08 g) at 0° C. and the mixture was stirred at room temperature for 2 hrs. Sodium sulfate decahydrate (0.65 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, and the filtrate was concentrated. The residue was subjected to silica gel column chromatography to give [3-[(4-{[2-(2-furyl)-5-methyl-1,3-oxazol-4-yl]methoxy}-3-methoxybenzyl)oxy]-1-(pyridin-3-ylmethyl)-1H-pyrazol-4-yl]methanol as colorless crystals (0.34 g, yield 52%) from a fraction eluted with ethyl acetate-methanol (10:1, v/v). Recrystallization from ethyl acetate-hexane gave colorless prism crystals. melting point: 90-91° C.
