Procedure

An amount of 3.7 gm (0.017 mol) of 3,4-dimethoxy-o-phenylenediacetonitrile is suspended in 10 ml of glacial acetic acid and then combined at 20° C. with 12 ml of 30% hydrobromic acid in glacial acetic acid. The mixture is stirred for a further three hours at ambient temperature, and the precipitate is subjected to suction filtration, washed with glacial acetic acid and then with acetone/ether, and dried.
