Reaction Steps

Reaction of pyridine-2-sulfonic acid 4-hydroxymethyl-benzylamide (140 mg, 0.50 mmol), Et3N (88 uL, 0.60 mmol), and MsCl (47 uL, 0.60 mmol) for 2 h at reflux followed by column chromatography on silica gel (CH2Cl2/MeOH 99:1) gave the title compound (67 mg, 45%) as a white solid. 1H NMR (300 MHz, CDCl3) δ 4.28 (d, 2H, J=6.0 Hz), 4.54 (s, 2H), 5.17 (br s, 1H), 7.23-7.49 (m, 4H), 7.47-7.52 (m, 1H), 7.88 (ddd, 1H, J=7.5, 7.5, 1.7 Hz), 7.97 (d, 2H, J=7.5 Hz), 8.69 (d, 1H, J=4.8 Hz). ES-MS m/z 319 (M+Na).
