実験手順

To a stirring solution of tert-butyl 4-(3-cyano-1-(4-cyano-3-fluorophenyl)-6-oxo-1,6-dihydropyridazin-4-yloxy)piperidine-1-carboxylate (example 34) (22 mg, 0.050 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 vacuum for 2 hours, 19 mg (100%) of 1-(4-cyano-3-fluorophenyl)-6-oxo-4-(piperidin-4-yloxy)-1,6-dihydropyridazine-3-carbonitrile HCl salt was obtained as an off-white solid. MS (ESI) 340 (M+H).
