実験手順

Into a 50-mL 3-necked round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed a solution of N-(2-(2-(2-(2-aminoethoxy)ethoxy)ethoxy)ethyl)-3-(6,8-dichloro-2-ethyl-1,2,3,4-tetrahydroisoquinolin-4-yl)benzenesulfonamide (100 mg, 0.18 mmol, 1.00 equiv) in DMF (3 mL), bis(2,5-dioxopyrrolidin-1-yl) 2,3-dihydroxysuccinate (Intermediate 168.1) (25 mg, 0.07 mmol, 0.45 equiv) and triethylamine (75 mg, 4.50 equiv). The resulting solution was stirred overnight at room temperature. The reaction progress was monitored by LCMS. The resulting mixture was concentrated under vacuum. The crude product was purified by Flash-Prep-HPLC with water: methanol (1:10-1:100). This resulted in 12.1 mg (5%) of N1,N4-bis(2-(2-(2-(2-(3-(6,8-dichloro-2-ethyl-1,2,3,4-tetrahydroisoquinolin-4-yl)phenylsulfonamido)ethoxy)ethoxy)ethoxy)ethyl)-2,3-dihydroxysuccinamide as yellow oil. 1H-NMR (300 MHz, DMSO, ppm): δ 7.70-7.60 (m, 8H), 7.53-7.49 (m, 6H), 6.88 (s, 2H), 5.61-5.59 (m, 2H), 4.38 (m, 2H), 4.24-4.22 (m, 2H), 3.78-3.72 (m, 2H), 3.58-3.48 (m, 2H), 3.43 (m, 7H), 3.43-3.40 (m, 11H), 3.27-3.20 (m, 5H), 2.91-2.87 (m, 6H), 2.76-2.70 (m, 2H), 2.61-2.55 (m, 3H), 1.04-0.99 (m, 6H). MS (m/z): 1235 [M+H]+.
