Procedure

Sodium borohydride (540 mg) was added to a solution of 3,5-dimethoxy-4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzaldehyde (10.0 g) in tetrahydrofuran (70 ml)-methanol (30 ml) at 0° C. After stirring for 1 hour, the reaction mixture was poured into water to give 3,5-dimethoxy-4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyl alcohol (9.25 g, yield 92%) as crystals. Recrystallization from ethyl acetate-hexane gave colorless prisms. m.p. 113-114° C.
