Reaction Steps
5-(1-benzoylpyrrolidin-2-yl)-N-(2,4-dimethoxybenzyl)-N-(thiazol-2-yl)naphthalene-2-sulfonamide (0.040 g, 0.065 mmol) was dissolved in DCM and TFA (0.1 mL, 1.298 mmol) was added. The reaction was stirred for 15 minutes at room temperature. The reaction was diluted with methanol and concentrated. The material was triturated in diethyl ether, filtered, and the solids were washed with diethyl ether. The solids were collected and vacuum dried overnight to afford 5-(1-benzoylpyrrolidin-2-yl)-N-(thiazol-2-yl)naphthalene-2-sulfonamide as a white solid. 1H NMR (400 MHz, DMSO-d6) δ=12.79 (br. s., 1H), 8.48 (s, 1H), 8.38 (d, J=8.8 Hz, 1H), 8.11-7.95 (m, 1H), 7.87 (d, J=9.3 Hz, 1H), 7.75-7.57 (m, 4H), 7.49 (br. s., 3H), 7.26 (br. s., 1H), 7.17-6.96 (m, 1H), 6.84 (d, J=4.2 Hz, 1H), 5.94 (br. s., 1H), 3.90 (br. s., 1H), 3.58 (br. s., 1H), 2.70-2.58 (m, 1H), 1.89 (br. s., 2H), 1.74 (br. s., 1H). m/z (ESI) 464.2 (M+H)+.
