反応手順

To a solution of 3-methoxy-4-[(5-methyl-2-pyridin-3-yl-1,3-oxazol-4-yl)methoxy]benzaldehyde (3.26 g) in tetrahydrofuran (50 mL)-ethanol (10 mL) was gradually added sodium borohydride (0.38 g) at room temperature. After stirring the reaction mixture at room temperature for 30 min, water was added, and the precipitated crystals were collected by filtration to give {3-methoxy-4-[(5-methyl-2-pyridin-3-yl-1,3-oxazol-4-yl)methoxy]phenyl}methanol as colorless crystals (3.00 g, yield 91%). Recrystallization from ethyl acetate-hexane gave colorless prism crystals. melting point: 117-118° C.
