Participants

Reaction Steps

A solution of bromine (0.96 g) in acetic acid (10 ml) was dropped into a solution of 3,4-dimethoxybenzaldehyde (1.0 g) in acetic acid (4 ml) and the mixture was stirred for three hours. Sodium thiosulfate was added to the reaction mixture, then sodium bicarbonate was added thereto and the mixture was filtered. The crude crystals collected by the filtration were recrystallized from chloroform-ether to give the title compound (0.83 g, 56%). The peaks of this compound in 1H-NMR (400 MHz, CDCl3) were as follows.
