실험 절차

tert-butyl 1-(3-methoxy-4-(methoxycarbonyl)phenyl)hydrazinecarboxylate (Intermediate #112) (4.86 g, 16.40 mmol) was added to a 4M solution of hydrogen chloride (61.5 mL, 246 mmol) in dioxane. The resulting solution was stirred at 20° C. for 5 hours. The reaction mixture was evaporated to dryness and the crude residue was triturated with Et2O to give a solid which was collected by filtration and dried under vacuum to give methyl 4-hydrazinyl-2-methoxybenzoate hydrochloride (3.50 g, 92%) as a pale green solid.
