실험 절차

A mixture of 22.6 g 5-bromoisatin (0.1 mole), 15.0 g 4,5-dimethyl-o-phenylene diamine (0.11 mole) and 400 ml acetic acid is boiled under reflux for 4 hours. After cooling the product is sucked, washed with ethanol and dried. Yield 29 g, 89%. Recrystallisation from pyridine gives needle shaped crystals with melting point 319°-322° C.
