Procedure

In 100 ml of dimethylformamide was dissolved 10 g of isovaniline, and 14 ml of N,N-diisopropylethylamine was added to the solution and the mixture was stirred. The liquid mixture was cooled to 0° C. and 7.2 ml of chloromethyl methyl ether was added to the mixture, and 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, washed with water and dried. Removal of the solvent by distillation gave 11.0 g (yield=85%) of 4-methoxy-3-methoxymethoxybenzaldehyde in the form of a yellow oil.
