Reaction Steps

Compound 248 was prepared following the procedure outlined in Example 208 using 1,4-diisocyanatobutane (7.64 mg, 0.545 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, 84.4 mg, 0.109 mmol). Purification by preparative HPLC gave the title compound (43.6 mg) as a TFA salt. 1H-NMR (400 MHz, CD3OD): δ 7.89 (d, 4H), 7.54 (s, 2H), 7.45 (d, 4H), 6.84 (s, 2H), 4.79-4.71 (m, 4H), 3.89-3.85 (dd, 2H), 3.59-3.56 (m, 17H), 3.49-3.43 (m, 14H), 3.28-3.23 (m, 5H), 3.14 (s, 7H), 3.09-3.04 (m, 9H), 1.42 (s, 4H). MS (m/z): 1233.03 [M+H]+.
