反応条件: temp:80.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of vanilin (76.1 g) in N,N-dimethylformamide (500 mL) is added successively 4-(2-chloroethyl)morpholine hydrochloride (130 g), sodium iodide (7.5 g), and potassium carbonate (207 g). The mixture is stirred at 80° C. for 15 hours. The reaction mixture is concentrated in vacuo. The residue is diluted with ethyl acetate, washed with saturated brine, dried over anhydrous sodium sulfate, and concentrated in vacuo. To the residue is added diisopropyl ether and the resultant crystals are collected by filtration to give 3-methoxy-4-(2-morpholinoethoxy)-benzaldehyde (112.6 g, yield; 85%) as orange crystals. MS (APCI) m/z: 266 [M+H]+ The reaction mixture is concentrated in vacuo The residue is diluted with ethyl acetate washed with saturated brine dried over anhydrous sodium sulfate concentrated in vacuo To the residue is added diisopropyl ether the resultant crystals are collected by filtration
