Reaction Steps

To a solution of 3-cyano-4-(4-cyano-3-fluorophenoxy)-5-fluorobenzene-1-sulfonyl chloride (Preparation 43, 27 mg, 0.153 mmol) in DCM (5 mL) was added 5-fluoro-2-aminopyridine (26 mg, 0.230 mmol) followed by pyridine (36 mg, 0.459 mmol, 0.037 mL) and the reaction was stirred at room temperature for 18 hours. The reaction was diluted with DCM (20 mL) and water (30 mL). The organic layer was separated and the aqueous re-extracted with DCM (2×30 mL). The combined organic layers were dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified by reverse phase chromatography eluting with (acetonitrile/0.1% formic acid) and (water/0.1% formic acid), gradient 5% to 60% to afford the title compound as colourless solid (21 mg, 31%).
