반응 단계

A solution of 3-chloro-4-(trifluoromethyl)phenol (Preparation 5, 50 mg, 0.26 mmol), 4-(bromomethyl)-2,5-difluoro-N-(methylsulfonyl)benzamide (Preparation 4, 84 mg, 0.26 mmol) and potassium carbonate (71 mg, 0.51 mmol) in dimethyl sulfoxide (5 mL) was stirred at room temperature for 16 hours. A 2M aqueous solution of hydrogen chloride was added to the reaction mixture. The resulting precipitate was filtered, washed with diethyl ether (5 mL) and dried. The material was purified by reverse phase column chromatography (12 g C-18 biotage cartridge; eluents: MeCN+0.1% formic acid, and H2O+0.1% formic acid; Gradient: 30% MeCN, followed by gradient to 100% MeCN, 100% MeCN. Fractions containing product were combined and concentrated in vacuo to afford the title compound as a colourless solid (65 mg, 56%).
