Compound 183 was prepared from intermediate 175.1 and bis(2,5-dioxopyrrolidin-1-yl) 2,2-dimethylmalonate (prepared using the methods outlined in example 168) following the procedure outlined in example 175. The crude product was purified by Prep-HPLC with acetonitrile:water (0.05% CF3COOH) (10%-100%). This resulted in 29.5 mg (5%) of a TFA salt of N1,N3-bis(2-(2-(2-(4-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)phenylsulfonamido)ethoxy)ethoxy)ethyl)-2,2-dimethylmalonamide as a white solid. 1H-NMR (300 MHz, CD3OD, ppm): δ 7.94-7.92 (m, 4H), 7.57 (m, 2H), 7.51-7.49 (m, 4H), 6.87 (m, 2H), 4.83-4.74 (m, 4H), 4.55-4.50 (m, 2H), 3.92-3.87 (m, 2H), 3.67-3.48 (m, 8H), 3.40-3.38 (m, 4H), 3.18 (s, 6H), 3.14-3.00 (m, 4H), 1.41 (s, 6H). MS (m/z): 551 [½M+H]+.
