Compound 220 was prepared following the procedure outlined in Example 219 using biphenyl-4,4′-disulfonyl dichloride (16.1 mg, 0.0459 mmol) and 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, 50 mg, 0.0917 mmol). Purification by preparative HPLC gave the title compound (16.7 mg) as a TFA salt. 1H-NMR (400 MHz, CD3OD): δ 7.96 (d, 4H), 7.88-7.85 (m, 5H), 7.78 (s, 2H), 7.61 (t, 2H), 7.47 (d, 2H), 6.78 (s, 2H), 4.74-4.69 (m, 3H), 4.45 (d, 2H), 3.88-3.83 (m, 2H), 3.62-3.59 (m, 2H), 3.55-3.53 (m, 9H), 3.52-3.43 (m, 17H), 3.13 (s, 6H), 3.11-3.03 (m, 8H). MS (m/z): 1371.02 [M+H]+.
