実験手順

To a solution of N-(2-(2-(2-(2-aminoethoxy)ethoxy)ethoxy)ethyl)-3-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)benzenesulfonamide (Compound 28, 50 mg, 0.0917 mmol) and DIEA (35.5 mg, 0.275 mmol) in dry DCM (0.183 mL) under N2 was added benzene-1,3-disulfonyl dichloride (12.7 mg, 0.0459 mmol) in DCM (0.183 mL). The reaction mixture was stirred at room temperature for 60 minutes at which point LCMS indicated complete conversion. The solvent was removed and the resulting residue brought up in 4 mL ACN/H2O solution (1:1). Filtration and purification by preparative HPLC gave the title compound (16.6 mg) as a TFA salt. 1H-NMR (400 MHz, CD3OD): δ 8.28 (s, 1H), 8.06 (d, 1H), 7.85 (d, 2H), 7.75 (d, 2H), 7.70 (s, 1H), 7.63 (t, 2H), 7.53 (m, 3H), 6.82 (s, 1H), 4.52 (d, 1H), 3.85 (d, 1H), 3.61-3.46 (m, 28H), 3.13 (s, 6H), 3.09-3.03 (m, 7H). MS (m/z): 1294.99 [M+H]+.
