Reaction Steps

Hydrogen chloride 4M in Dioxan (100 mL, 399.60 mmol) was added to 4-Hydrazinobenzoic acid (15.2 g, 99.90 mmol) in MeOH (200 mL). The resulting suspension was stirred at 90° C. for 5 hours. After cooling to 20° C. the precipitate was collected by filtration, washed with Et2O (100 mL) and dried under vacuum to afford 2-(4-(methoxycarbonyl)phenyl)hydrazinium chloride (16.50 g, 82%) as a cream crystalline solid.
