実験手順

3,3-Difluoroazetidine hydrochloride (98 mg, 0.76 mmol) was added to a suspension of 5-chloro-4-(5-chloro-6-fluoropyridin-3-yloxy)-2-fluoro-N-(methylsulfonyl)benzamide (Example 19, 150 mg, 0.38 mmol) and potassium carbonate (74 mg, 0.53 mmol) in dimethylsulfoxide (1 mL). The reaction mixture was stirred at 90° C. in the microwave for 15 hours. The reaction mixture was diluted with water (10 mL) and extracted with ethyl acetate (3×10 mL). The combined organic layers were dried (MgSO4), filtered and concentrated in vacuo. The crude compound was purified by reverse phase preparative HPLC eluting with acetonitrile:water (from 5:95 to 95:5) to give the title compound as a colourless solid (44 mg, 25%).
