Procedure
A mixture of 4-(4-chloromethyl-1,3-thiazol-2-yl)morpholine (1.00 g), potassium carbonate (0.64 g), vanillin (0.70 g) and N,N-dimethylformamide (30 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-methoxy-4-[(2-morpholin-4-yl-1,3-thiazol-4-yl)methoxy]benzaldehyde as colorless crystals (1.33 g, 86%). Recrystallization from ethyl acetate-hexane gave colorless prism crystals. melting point: 122-123° C.
