Reaction Steps

4-tert-Butyl —N-[5-chloro-2-(6-fluoro-pyridine-3-carbonyl)-pyridin-3-yl]-N-methoxymethyl-benzenesulfonamide (444 mg, 0.899 mmol) was dissolved in DMF (5 mL). KCN (300 mg, 4.6 mmol) was then added and the reaction mixture was heated to 60° C. for 2 hours. Additional KCN (110 mg, 1.7 mmol) was then added and the reaction was stirred for another 2 hours. The solvent was removed under reduced pressure and the resulting brown oil purified by column (1:4 EtOAc/hexanes) to give 172 mg (0.345 mmol, 38% yield). MS calc'd for C24H24ClN4O4S (MH+): 499.1, found 499.1.
