To a solution of N-(3-morpholin-4-yl-phenyl)-hydrazinecarboxylic acid tert-butyl ester (468 mg, 1.60 mmol) in methanol (20 mL) was added a solution of 4 N HCl in dioxane (10 mL). The mixture was stirred at room temperature overnight, then concentrated to give (3-morpholin-4-yl-phenyl)-hydrazine 3 HCl salt (484 mg, 100%) as a yellow solid. MS (ES+): m/z=194.1; 1H NMR (CD3OD, 500 MHz): δ 3.60-3.71 (m, 4H), 4.06-4.15 (m, 4H), 7.06 (d, 1H), 7.26-7.35 (m, 2H), 7.50-7.58 (m, 1H).
