Compound 218 was prepared following the procedure outlined in Example 168 using (2R,3R)-bis(2,5-dioxopyrrolidin-1-yl) 2,3-dihydroxysuccinate (10.2 mg, 0.0298 mmol) and N-(2-(2-(2-aminoethoxy)ethoxy)ethyl)-3-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)benzenesulfonamide (Compound 168.2, 30 mg, 0.0597 mmol). Purification by preparative HPLC gave the title compound (5.1 mg) as the TFA salt. 1H-NMR (400 MHz, CD3OD): δ 7.92 (d, J=7.8 Hz, 2H), 7.82 (m, 2H), 7.67 (t, J=7.8 Hz, 2H), 7.57 (m, 2H), 7.55 (d, J=6.9 Hz, 2H0, 6.86 (m, 2H), 4.84 (s, 2H), 4.79 (s, 2H), 4.54 (d, 2H), 4.48 (s, 2H), 3.92 (m, 2H), 3.53 (m, 22H), 3.18 (s, 6H), 3.07 (t, J=5.4 Hz, 4H). MS (m/z): 1119.04 [M+H]+.
