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) (54.5 mg, 0.1 mmol) in DMF (0.20 mL) was added DIEA (15.5 mg, 0.12 mmol) and bis(2,5-dioxopyrrolidin-1-yl) octanedioate (18.4 mg, 0.05 mmol). The reaction was stirred at room temperature for 3 hours at which point an additional 0.03 mmol of compound 28 was added. After a further hour the solvent was removed and the resulting residue dissolved in acetonitrile/water (1:1) and purified by preparative HPLC to give the title compound (17.4 mg) as a TFA salt. 1H-NMR (400 MHz, CD3OD): 7.89 (d, 2H), 7.78 (s, 2H), 7.64 (t, 2H), 7.52 (m, 4H), 6.83 (s, 2H), 4.81 (m, 4H), 4.45 (d, 2H), 3.89 (dd, 2H), 3.61 (m, 18H), 3.55 (m, 10H), 3.47 (m, 5H), 3.33 (m, 5H), 3.14 (s, 7H), 3.04 (t, 4H), 2.16 (t, 4H), 1.55 (m, 4H), 1.29 (m, 4H). MS (m/z): 1231.87 (M+H).
