Versuchsvorschrift

Sodium borohydride (1.18 g) was added to a solution of 3-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzaldehyde (18.3 g) in methanol (50 ml)-tetrahydrofuran (100 ml) in portions at 0° C. After stirring for 30 minutes, water was added to the reaction mixture and extracted with ethyl acetate. The ethyl acetate layer was washed with an aqueous saturated solution of sodium chloride, dried (MgSO4) and concentrated. The remaining crystals were recrystallized from ethyl acetate-hexane to obtain 3-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzylalcohol (15.5 g, yield 84%) as colorless crystals. m.p. 101-102° C.
