Reaction Steps

Triethylamine (0.21 mL, 1.51 mmol) was added to a mixture of 5-chloro-4-[5-chloro-6-fluoropyridin-3-yl)oxy]-2-fluoro-N-(methylsulfonyl)benzamide (Example 19, 150 mg, 0.38 mmol) and 3,3-difluoropyrrolidine hydrochloride salt (60 mg, 0.41 mmol), in DMSO (3.8 mL) and the reaction heated at 80° C. for 120 hours. The mixture was diluted to 5 mL by the addition of water and the mixture purified by preparative HPLC. The title compound was obtained as a beige solid (49 mg, 27%).
