実験手順

To a solution of a TFA salt 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) (47 mg, 0.061 mmol) in DMF (0.20 mL) was added 1,4-diisocyanatobutane (4.0 mg, 0.03 mmol) followed by diisopropylethylamine (15 mg, 0.12 mmol). After stirring at room temperature for 30 minutes, the reaction was purified by preparative HPLC to give the title compound (31 mg) as a TFA salt. 1H-NMR (400 mHz, CD3OD) δ 7.88 (m, 2H), 7.75 (m, 2H), 7.63 (m, 2H), 7.54 (m, 4H), 6.83 (m, 2H), 4.74 (m, 4H), 4.48 (m, 2H), 3.87 (m, 2H), 3.62-3.55 (m, 14H), 3.51-3.43 (m, 12H), 3.24 (m, 4H), 3.14 (s, 6H), 3.05 (m, 8H), 1.43 (m, 4H). MS (m/z): 1230.99 [M+H]+.
