実験手順

Into a 50-mL round-bottom flask, was placed 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) (150 mg, 0.28 mmol, 1.00 equiv) in DMF (5 mL), triethylamine (56 mg, 0.55 mmol, 2.01 equiv) and bis(2,5-dioxopyrrolidin-1-yl) 2,2′-oxydiacetate (intermediate 178.1) (44 mg, 0.14 mmol, 0.49 equiv). The resulting solution was stirred overnight at room temperature, at which time the mixture was concentrated under vacuum. The crude product (150 mg) was purified by preparative HPLC with the following conditions: Column, C18 silica gel; mobile phase, methanol/water=0.05/100 increasing to methanol/water=90/100 within 19 min; Detector, UV 254 nm. This resulted in 72.4 mg (44%) of the title compound as a white solid. 1H-NMR (300 MHz, CD3OD, ppm): δ 7.79 (d, J=7.2 Hz, 2H), 7.71 (s, 2H), 7.49˜7.58 (m, 4H), 7.36-7.37 (m, 2H), 6.82 (s, 2H), 4.39-4.44 (m, 2H), 4.06 (s, 4H), 3.80 (d, J=16.2 Hz, 2H), 3.65 (d, J=16.2 Hz, 2H), 3.55-3.61 (m, 16H), 3.43˜3.52 (m, 12H), 3.02˜3.08 (m, 6H), 2.65-2.70 (m, 2H), 2.49 (s, 6H). MS (m/z): 1190 [M+H]+
