N-(2-(2-(2-(2-azidoethoxy)ethoxy)ethoxy)ethyl)-3-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)benzenesulfonamide (intermediate 28.1) (1.035 g, assume 1.41 mmol) was dissolved in a 10:1 THF:water solution (26.5 mL) and placed under N2. PMe3 (165 mg, 2.18 mmol) was added and the reaction stirred overnight. The solvent was removed and the resulting residue brought up in EtOAc (100 mL) and washed with NaHCO3 (100 mL) and brine (100 mL). After drying the organic layer over Na2SO4, the solvent was removed to give 446 mg of the title compound (58% over two steps) as an oil. A portion of the crude product was purified by preparative HPLC to give the title compound as a TFA salt. 1H-NMR (400 mHz, CD3OD) δ 7.87 (m, 1H), 7.73 (m, 1H), 7.67 (t, j=7.7 Hz, 1H), 7.54 (m, 2H), 6.82 (s, 1H), 4.8-4.6 (m, 4H), 4.46 (m, 1H), 3.86 (m, 1H), 3.69 (m, 2H), 3.66 (s, 3H), 3.61 (m, 2H), 3.55 (m, 2H), 3.12 (m, 4H), 3.03 (t, j=5.4 Hz, 1H).
