実験手順

To 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) (1.2 g, 2.28 mmol, 1.00 equiv) in DMF (8 mL) was added bis(2,5-dioxopyrrolidin-1-yl) 2,3-dihydroxysuccinate (intermediate 168.1) (393 mg, 1.14 mmol, 0.50 equiv) and triethylamine (1.5 g, 14.82 mmol, 6.50 equiv) and the resulting solution was stirred overnight at room temperature. The mixture was concentrated under vacuum and the crude product was purified by Flash-Prep-HPLC with the following conditions: Column, silica gel; mobile phase, methanol:water=1:9 increasing to methanol:water=9:1 within 30 min; Detector, UV 254 nm. This resulted in 591 mg (43%) of N1,N4-bis(2-(2-(2-(2-(3-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)phenylsulfonamido)ethoxy)ethoxy)ethoxy)ethyl)-2,3-dihydroxysuccinamide as a light yellow solid. 1H-NMR (300 MHz, CD3OD, ppm): δ 7.92 (d, J=7.8 Hz, 2H), 7.81 (m, 2H), 7.67 (t, J=7.8 Hz, 2H, 7.57 (m, 2H), 7.55 (d, J=6.9 Hz, 2H), 6.85 (m, 2H), 4.78 (s, 2H), 4.77 (s, 2H), 4.54 (d, J=40.2 Hz, 2H), 4.48 (s, 2H), 3.92 (m, 2H), 3.53 (m, 30H), 3.18 (s, 6H), 3.07 (t, J=5.4 Hz, 4H). MS (m/z): 603 [½M+H]+.
