실험 절차
To N-(2-(2-(2-aminoethoxy)ethoxy)ethyl)-3-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)benzenesulfonamide (intermediate 168.2) (150 mg, 0.30 mmol, 1.00 equiv) in DMF (2 mL) was added triethylamine (60 mg, 0.59 mmol, 1.98 equiv) and intermediate 177.1 (47 mg, 0.15 mmol, 0.50 equiv) and the resulting solution was stirred overnight. The mixture was then concentrated under vacuum and the crude product (150 mg) was purified by Flash-Prep-HPLC with the following conditions: column, C18 silica gel; mobile phase, methanol/water=0.05/100 increasing to methanol/water=90/100 within 25 min; Detector, UV 254 nm. This resulted in 53.1 mg (33%) of N1,N4-bis(2-(2-(2-(3-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)phenylsulfonamido)ethoxy)ethoxy)ethyl)succinamide as a white solid. 1H-NMR (300 MHz, CD3OD, ppm): δ 7.77-7.80 (m, 2H), 7.71 (s, 2H), 7.48-7.57 (m, 4H), 7.36-7.37 (m, 2H), 6.82 (s, 2H), 4.39-4.44 (m, 2H), 3.79 (d, J=15.9 Hz, 2H), 3.66 (d, J=16.2 Hz, 2H), 3.45-3.57 (m, 16H), 3.35-3.37 (m, 4H), 3.03-3.08 (m, 6H), 2.65-2.71 (m, 2H), 2.49-2.50 (m, 10H).
