A mixture of 4-(4-chloromethyl-5-methyl-1,3-thiazol-2-yl)morpholine (5.0 g), vanillin (3.27 g), potassium carbonate (2.97 g) and N,N-dimethylformamide (100 mL) was stirred at 90° C. for 3 hrs. Water was poured into the reaction mixture, and the precipitated crystals were collected by filtration to give 3-methoxy-4-[(5-methyl-2-morpholin-4-yl-1,3-thiazol-4-yl)methoxy]benzaldehyde as crystals (7.25 g, yield 96%). Recrystallization from hexane-ethyl acetate gave colorless prism crystals. melting point: 127-128° C.
