Phenylhydrazine (1.3 g, 12 mmol) is dissolved in ethanol (50 ml) and admixed under argon with 6-chlorophenanthridine (A. G. Mikhailovskii, V. S. Shklyaev, Chem. Heterocycl. Comp. 1992, 445) (2.1 g, 10 mmol). The mixture is stirred under reflux for 16 h. After cooling to room temperature, the mixture is concentrated and the resulting precipitate is filtered off and washed with methyl tert-butyl ether. Yield: 2.6 g (82%).
