Procedure

Here, 3,4-dimethoxy-o-phenylene-diacetonitrile (3.7 g, 0.017 mol) is suspended in glacial acetic acid (10 ml) and mixed with 30% hydrobromic acid (12 ml) in glacial acetic acid at 20° C. The mixture is stirred for 3 hours at ambient temperature, the precipitate is suction filtered, washed with glacial acetic acid and then with acetone/ether and dried.

Workup

  1. filtrationfiltered
  2. washwashed with glacial acetic acid
  3. dry with materialwith acetone/ether and dried
