To a mixture of N-(3-(4-fluorophenoxy)benzyl)-4-phenylbutan-1-amine (100 mg, 28.6 mmol, 1.0 eq) in DCM (5 mL), was added triethylamine (86 mg, 85 mmol, 3 eq) followed by 2-hydroxy-3,5-dichlorobenzenesulfonyl chloride (75 mg, 28.6 mmol, 1.0 eq). The reaction mixture was stirred at ambient temperature for 4 h before being diluted with DCM (100 mL) and washed with water. The organic layer was dried over anhydrous Na2SO4 and evaporated under reduced pressure. The residue was purified by preparative HPLC to afford the title compound (45 mg, 28%); 1H NMR (400 MHz, CD3OD) δ 7.67-7.66 (d, 1H), 7.58-7.57 (d, 1H), 7.30-7.26 (t, 1H), 7.23-7.20 (t, 2H), 7.15-7.00 (m, 6H), 6.97-6.94 (m, 2H), 6.88-6.84 (m, 2H), 4.47 (s, 2H), 3.26-3.22 (t, 2H), 2.46-2.43 (t, 2H), 1.42-1.34 (m, 4H). MS (ESI): 574.0 (M−H)−.
