To a mixture of 4-[5-methyl-2-(2-naphthyl)-4-oxazolylmethoxy]benzaldehyde (6.00 g), tetrahydrofuran (80 mL) and methanol (20 mL) was gradually added sodium borohydride (330 mg) at room temperature. After stirring for 30 min., water was added to the reaction mixture, and the precipitated crystals were collected by filtration and recrystallized from acetone-methanol to give colorless prism crystals (5.76 g, 95%) of 4-[5-methyl-2-(2-naphthyl)-4-oxazolylmethoxy]benzyl alcohol. melting point: 181-182° C.
