Reaction Steps

Compound 230 was prepared by following the procedure outlined in Example 215 using phthalic acid (8.0 mg, 0.0484 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, 75 mg, 0.0968 mmol). Purification by preparative HPLC gave the title compound (35.4 mg) as a TFA salt. 1H-NMR (400 MHz, CD3OD): δ 7.87 (d, 2H), 7.76 (s, 2H), 7.63 (t, 2H), 7.50 (m, 8H), 6.79 (s, 2H), 4.83-4.73 (m, 4H), 4.65 (d, 2H( ), 3.85 (q, 2H), 3.62-3.39 (m, 36H), 3.10 (s, 6H), 3.02 (t, 4H). MS (m/z): 1223.00 [M+H]+.
