Procedure

A mixture of 4-formylbenzoic acid (7.5 g), triethylamine (5.2 g) and p-methoxybenzyl chloride (7.6 g) in dimethylformamide (75 ml) was stirred at room temperature for 2 hours and then at 80° C. for 6 hours. The reaction mixture was diluted with water and extracted with diethyl ether. The ether extract was washed with aqueous sodium bicarbonate and then water, dried over anhydrous sodium sulfate and evaporated to give 4-formylbenzoic acid p-methoxybenzyl ester which was then converted into 4-carboxybenzoic acid p-methoxybenzyl ester by the procedure similar to that described in Example 185.
