To a mixture of 2-[4-[(5-methyl-2-phenyl-4-thiazolyl)methoxy]benzyloxy]nicotinaldehyde (2.16 g), tetrahydrofuran (30 ml) and ethanol (30 mL) was added sodium borohydride (0.20 g) at 0° C., and the mixture was stirred at room temperature for 30 min. Water was added to the reaction mixture, and the precipitated solid was collected by filtration, and dried with air to give crystals (2.12 g, 97%) of [2-[4-[(5-methyl-2-phenyl-4-thiazolyl)methoxy]benzyloxy]-3-pyridyl]methanol. Recrystallization from ethyl acetate-hexane gave colorless prism crystals. melting point: 111-112° C.
