Reaction Steps

Compound 238 was prepared following the procedure outlined in Example 208 using 1,4-diisocyanatobutane (5.64 mg, 0.402 mmol) and N-(2-(2-(2-aminoethoxy)ethoxy)ethyl)-4-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)benzenesulfonamide (Compound 175.1, 58.8 mg, 0.805 mmol). Purification by preparative HPLC gave the title compound (13.8 mg) as a TFA salt. 1H-NMR (400 MHz, CD3OD): δ 7.86 (d, J=8 Hz, 2H), 7.72 (s, 2H), 7.61 (t, 2H), 7.52 (s, 2H), 7.47 (d, J=7 Hz, 2H), 7.18 (s, 5H), 7.78 (s, 2H), 4.77-4.68 (m, 5H), 4.48-4.40 (m, 2H), 3.35-3.28 (m, 2H), 3.56-3.51 (m, 16H), 3.45 (t, J=5 Hz, 5H), 3.35-3.32 (m, 10H), 3.09 (s, 6H), 3.03 (t, J=5 Hz, 3H). MS (m/z): 1145.01 [M+H]+.
