Procedure
A mixture of 3-(4-chloromethyl-5-methyl-1,3-oxazol-2-yl)benzonitrile (26.3 g), vanillin (17.19 g), anhydrous potassium carbonate (15.62 g) and N,N-dimethylformamide (300 mL) was stirred at 90° C. for 2 hrs. Water was poured into the reaction mixture, and the precipitated crystals were collected by filtration to give 3-{4-[(4-formyl-2-methoxyphenoxy)methyl]-5-methyl-1,3-oxazol-2-yl}benzonitrile as colorless crystals (33.9 g, yield 86%). Recrystallization from ethyl acetate-hexane gave colorless prism crystals. melting point: 166-167° C.
