Procedure

Compound 233 was prepared following the procedures outlined in Example 215 using terephthalic acid (10.4 mg, 0.0628 mmol) and N-(2-(2-(2-(2-aminoethoxy)ethoxy)ethoxy)ethyl)-4-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)benzenesulfonamide (Compound 82, 97.2 mg, 0.1255 mmol). Purification by preparative HPLC gave the title compound (38.9 mg) as a TFA salt. 1H-NMR (400 MHz, CD3OD): δ 7.83 (m, 10H), 7.85 (s, 2H), 7.42 (d, 4H), 6.83 (s, 1H), 3.66-3.55 (m, 28H), 3.46-3.39 (m, 11H), 3.12 (s, 7H), 3.04 (t, 4H). MS (m/z): 1223.14 [M+H]+.
