실험 절차

To a solution of 5-amino-3-[(4,6-dimethylpyridin-2-yl)amino]pyridine-2-carbonitrile (PrepEx 1.8) (150 mg, 0.63 mmol) in DCM (5 mL) was added triethylamine (0.26 mL, 1.88 mmol) followed by the dropwise addition of tert-butyl [2-(chlorosulfonyl)ethyl]carbamate (25% w/w in DCM, 920 mg, 0.94 mmol). The reaction mixture was stirred for 3 hours at room temperature. Additional tert-butyl [2-(chlorosulfonyl)ethyl]carbamate (25% w/w in DCM, 920 mg, 0.94 mmol) was added and the reaction mixture was stirred for 16 hours. The reaction mixture was diluted with ethyl acetate and saturated aqueous sodium bicarbonate. The organics were separated, dried over magnesium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by chromatography on silica gel to afford tert-butyl [2-({6-cyano-5-[(4,6-dimethylpyridin-2-yl)amino]pyridin-3-yl}sulfamoyl)ethyl]carbamate. MS ESI calc'd. for C20H27N6O4S [M+H]+ 447. found 447. 1H NMR (500 MHz, DMSO-d6) δ 10.70 (s, 1H), 9.19 (s, 1H), 8.50 (s, 1H), 8.01 (s, 1H), 6.86 (t, J=5.5 Hz, 1H), 6.73 (s, 1H), 6.65 (s, 1H), 3.41 (t, J=6.7 Hz, 2H), 3.32-3.29 (m, 2H), 2.31 (s, 3H), 2.22 (s, 3H), 1.30 (s, 9H).
