Participants

Reaction Steps

To a solution of N-(3-(aminomethyl)benzyl)-3,5-dichloro-2-hydroxy-N-(4-(trifluoromethyl)benzyl)benzenesulfonamide (60 mg, 0.12 mmol) in DMF (2 mL) were added N,N-diisopropylethylamine (0.08 mL, 0.46 mmol) and 1,1′-carbonyldiimidazole (20.6 mg, 0.13 mmol). The resulting mixture was stirred at it for 1 h under nitrogen, then 1-(2-chlorophenyl)piperazine monohydrochloride (29.6 mg, 0.13 mmol) was added. The mixture was stirred overnight. The mixture was concentrated and purified by preparative HPLC. Fractions containing the desired product were combined, concentrated and lyophilized to give white solid (54 mg, 62%). 1H NMR (MeOD-d4): δ 7.57 (d, J=2.8 Hz, 1H), 7.52 (d, J=2.8 Hz, 1H), 7.40 (d, J=8.3 Hz, 2H), 7.28 (m, 1H), 7.21 (d, J=8.3 Hz, 2H), 7.15 (m, 1H), 7.06 (m, 4H), 6.92 (m, 1H), 6.88 (m, 1H), 4.45 (s, 2H), 4.41 (s, 2H), 4.21 (s, 2H), 3.50 (t, J=5.0 Hz, 4H), 2.93 (t, J=5.0 Hz, 4H); MS (ESI): (M+H)+=743.2.
