実験手順
A mixture of 5-chloromethyl-4-methyl-2-phenyl-1,3-thiazole (2.30 g), vanillin (1.49 g), potassium carbonate (1.35 g) and N,N-dimethylformamide (50 mL) was stirred at 90° C. for 3 hrs. Water was poured into the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate and concentrated to give 3-methoxy-4-[(4-methyl-2-phenyl-1,3-thiazol-5-yl)methoxy]benzaldehyde as pale-yellow crystals (3.02 g, yield 91%). Recrystallization from ethyl acetate-hexane gave colorless prism crystals. melting point: 118-119° C.
