실험 절차

To a stirring solution of methyl 4-(1-(tert-butoxycarbonyl)piperidin-4-yloxy)-1-(4-cyano-3-fluorophenyl)-6-oxo-1,6-dihydropyridazine-3-carboxylate (142 mg, 0.30 mmol) in DCM (3 mL) at room temperature under argon was added 4 M HCl in dioxane (0.375 mL, 1.5 mmol). The reaction mixture was stirred at room temperature overnight. Et2O (10 mL) was added to the reaction mixture. The solid product was collected by filtration and further washed with ether (2 mL×2). After drying under reduced pressure for 2 hours, 105 mg of methyl 1-(4-cyano-3-fluorophenyl)-6-oxo-4-(piperidin-4-yloxy)-1,6-dihydropyridazine-3-carboxylate HCl salt was obtained as an off-white solid. MS (ESI) 373 (M+H).
