Reaction Steps

To a solution of [bis-(4-chloro-phenyl)-methylene]-hydrazine from Step 1 (2.0 g, 7.5 mmol) in CHCl3 (20 mL) was added MnO2 (5.0 g, 57 mmol). The resulting reaction mixture was stirred 1 h at 21° C., then filtered on a bed of MgSO4 and the filtrate concentrated to provided the diazo bis-(4-chloro-phenyl)-methane compound as a purple solid.
