A mixture of 4-[2-(5-methyl-2-phenyl-4-oxazolyl)ethoxy]benzyl chloride (6.4 g), powdered potassium cyanide (4.0 g) and N,N-dimethylformamide (50 ml) was stirred for two hours at 60° C. The reaction mixture was poured into water, which was subjected to extraction with ethyl acetate. The ethyl acetate layer was washed with water and dried (MgSO4), then the solvent was distilled off to leave 4-[2-(5-methyl-2-phenyl-4-oxazolyl)ethoxy]benzyl cyanide (5.2 g, 81%). The product was recrystallized from ethyl acetate--hexane to afford colorless needles, m.p.109°-110° C.
