Procedure

In 320 ml of dimethylformamide was dissolved 3.2 g of vaniline, and 44.8 g of N,N-diisopropylethylamine was added to the solution and the mixture was stirred. The liquid mixture was cooled to 0° C. and 18.1 ml of chloromethyl methyl ether was added to the liquid mixture. The temperature was elevated to room temperature and the mixture was stirred for 5 hours. After the reaction, a large quantity of water was added to the reaction mixture, and the mixture was extracted with diethyl ether and the solvent was removed from the extract by distillation. The obtained residue was allowed to stand under ice cooling, and the obtained solid was washed with petroleum ether and recovered by filtration to obtain 34.0 g (yield=83%) of intended 3-methoxy-4methoxymethoxybenzaldehyde.
