Reaction Steps

Compound 231 was prepared following the procedure outlined in Example 215 using terephthalic acid (11.4 mg, 0.0684 mmol) and 4-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)-N-(2-(2-(2-hydroxyethoxy)ethoxy)-ethyl)benzenesulfonamide (Compound 175.1, 100 mg, 0.136 mmol). Purification by preparative HPLC gave the title compound (9.8 mg) as a TFA salt. 1H-NMR (400 MHz, CD3OD): δ 7.86-7.85 (m, 9H), 7.83 (s, 2H), 7.50 (s, 1H), 7.41 (d, 4H), 6.80 (s, 1H), 3.68-3.42 (m, 26H), 3.34 (m, 2H), 3.09-3.01 (m, 12H). MS (m/z): 1135.07 [M+H]+.
