Diisopropylethylamine → N-(4-((3,5-Dichloro-N-(4-fluorobenzyl)-2-hydroxyphenylsulfonamido)methyl)benzyl)-N-(4-fluorobenzyl)-6-(trifluoromethyl)pyridine-3-sulfonamide

Participants

Reaction Steps

To a solution of 3,5-dichloro-N-(4-fluorobenzyl)-N-(4-((4-fluorobenzylamino)methyl)benzyl)-2-hydroxybenzenesulfonamide (47 mg, 0.10 mmol) in CH2Cl2 (1 mL) were added 6-(trifluoromethyl)pyridine-3-sulfonyl chloride (25 mg, 0.10 mmol, Aldrich) and diisopropylethylamine (0.042 mL, 0.30 mmol). The reaction mixture was stirred at rt for 2 h, and then concentrated. The residue was dissolved in methanol and purified by prep HPLC to give the title compound (24.0 mg, 57%) as a white solid. 1H NMR (DMSO-d6) δ 11.17 (br s, 1H), 9.15 (s, 1H), 8.50 (d, 1H, J=8.1 Hz), 8.11 (d, 1H, J=8.1 Hz), 7.83 (d, 2H, J=2.3 Hz), 7.56 (d, 1H, J=2.3 Hz), 7.17-6.97 (m, 12H), 4.40 (s, 2H), 4.39 (s, 2H), 4.37 (s, 2H), 4.34 (s, 2H); MS (ESI): 786.1 (M+H)+.
