Reaction Steps

To a solution of 5-amino-4-(2-fluoro-4-iodophenylamino)-1-methylpyridin-2(1H)-one (62.3 mg, 0.174 mmol) in dry pyridine (3 mL) at 0° C. (ice-salt bath), was added cyclopropanesulfonyl chloride (29 mg, 0.206 mmol). The resultant reaction mixture was allowed to warm to room temperature and stirred for 16 hours. Aqueous HCl (1N) (5 mL) was added and the mixture stirred for 15 minutes, resulting in the formation of a precipitate which was isolated by filtration, dried under vacuum, to afford the desired compound as a tan solid. (64 mg, 79% yield)
