Reaction Steps

2-Amino-N-methoxy-N-methyl-isonicotinamide (575 mg, 3.16 mmol) was dissolved in pyridine (4 mL), followed by the addition of methanesulfonyl chloride (0.73 mL, 9.48 mmol). The reaction was subsequently warmed to 40° C. and stirred 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.
