To a solution of 3-methoxy-4-[(5-methyl-2-morpholin-4-yl-1,3-thiazol-4-yl)methoxy]benzaldehyde (7.00 g) in tetrahydrofuran (100 mL)-ethanol (30 mL) was gradually added sodium borohydride (0.76 g) at room temperature. After stirring the reaction mixture at room temperature for 2 hrs, water was added, and the mixture was extracted with ethyl acetate. The organic layer was washed with water, dried over anhydrous magnesium sulfate and concentrated to give {3-methoxy-4-[(5-methyl-2-morpholin-4-yl-1,3-thiazol-4-yl)methoxy]phenyl}methanol as colorless crystals (6.29 g, yield 89%). Recrystallization from ethyl acetate-hexane gave colorless prism crystals. melting point: 121-122° C.
