Procedure

To a solution of 2-hydrazinylpyridine-4-carbonitrile (2.13 g, 16 mmol, PREPARATION 2) in EtOAc (10 mL) was added HCl (4 M in EtOAc, 15 mL) at rt. It was then stirred at rt for 30 min. The reaction mixture was filtered and washed with EtOAc and dried to give the title compound (3.13 g, 95%) as a yellow solid.
