Versuchsvorschrift

A 500 mL pressure flask was charged with 2,6-dichloro-3-nitrobenzonitrile (30.0 g, 138 mmol) and a 5.1 M solution of ammonia in EtOH (170 mL). The flask was sealed and heated in an oil bath at 80° C. with stirring for 1.5 h. The cooled solution was filtered, the crystals washed with water and dried to yield 2-amino-6-chloro-3-nitrobenzonitrile (18.4 g, 68%), mp 181-184° C.; MS (ES−) 196, 198 (M−H−).
