Participants

Reaction Steps

To a solution of 4-{[2-(2-furyl)-5-methyl-1,3-oxazol-4-yl]methoxy}-3-(methoxymethoxy)benzaldehyde (15.50 g) in tetrahydrofuran (100 mL)-ethanol (50 mL) was gradually added sodium borohydride (1.71 g) at 0° C. After stirring at room temperature for 2 hrs, water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate and concentrated to give (4-{[2-(2-furyl)-5-methyl-1,3-oxazol-4-yl]methoxy}-3-(methoxymethoxy)phenyl)methanol as colorless crystals (14.11 g, yield 91%). Recrystallization from ethyl acetate-hexane gave colorless prism crystals. melting point: 92-93° C.
