反応手順
48% aqueous HBr (8.8 M) (3.4 ml, 30 mmol) was slowly added to a stirred solution of 3,4-dichloroacetophenone (1.89 g, 10 mmol) in DMSO (17 ml). The solution was stirred in an open flask at 55° C. for 24 hours. The solution was poured onto ice, the solid product was filtered, washed with water, and redissolved in ethanol (18 ml). 4,5-Dinitro-1,2-phenylene-diamine (890 mg, 4.5 mmol) was added and the mixture was heated to reflux for 4 hours.
