Procedure

To 60 ml acetic acid were added in order 1.48 g (14 mmol) 2-hydrazinopyridine and 3.8 g (14 mmol) freshly prepared 4,5-di-morpholino-1,2-benzoquinone [Brackman and Havinga, Rec. trav. chim Pays-bas 74, 937 (1955)] at room temperature. The mixture was stirred overnight and the solvent taken off on a rotary evaporator. After dilution with water, the solid residue was filtered off, washed with water and air dried. The product was extracted twice with hot acetonitrile leaving 1.97 g product. The extract yielded another 1.02 g on cooling. Yield 3.0 g (59%).
