실험 절차

To a stirred, room temperature solution of n-butanol (0.81 g, 10.93 mmol, 1.1 equiv.) in THF (20 mL) was slowly added 1.0 M sodium bis(trimethylsilyl)amide in THF (12 mL, 12 mmol, 1.2 equiv.). The reaction mixture was stirred for 0.5 hours, then it was transferred to a solution of 2-(3,4-difluorophenyl)-4,5-dichloro-3(2H)-pyridazinone (2.88 g, 10.4 mmol, 1.0 equiv.) in THF (80 mL). The resulting reaction mixture was stirred for 0.5 hours at room temperature to provide the title compound (2.5 g, 79.4%).
