Reaction Steps

To a solution of N-[2-(2-amino-pyridine-4-carbonyl)-5-chloro-pyridin-3-yl]-N-methoxymethyl-4-methyl-3-trifluoromethyl-benzenesulfonamide (140 mg, 0.272 mmol) in pyridine (0.75 mL) was added methanesulfonyl chloride (0.042 mL, 0.544 mmol). The reaction was warmed to 50° C. and stirred 2.5 h. The resultant mixture was quenched with 10% HCl, diluted with EtOAc, and the organic layer washed with 10% HCl and saturated sodium bicarbonate. The combined organics were dried with sodium sulfate, concentrated in vacuo, and purified via automated silica gel chromatography to produce the desired sulfonamide.
