Reaction Steps

1-(1-(4-Chlorophenyl)cyclobutyl)-7-(2-(propylsulfonamido)ethoxy)-1,2,3,4-tetrahydroisoquinolinium chloride (187 mg, 0.374 mmol, example 4), triethylamine (91 mg, 0.897 mmol), Pd/C (11.95 mg, 0.011 mmol) were suspended in dry MeOH (5 ml) and treated with hydrogen gas at ambient pressure for 14 h. The solvent was removed and the residue was purified by column chromatography using silica gel dichloromethane/methanol (97:3→95:5) as the eluent. The product was transferred into the hydrochloride with isopropylether and HCl dissolved in isopropanol (6%). The product was obtained as a white powder (68.0 mg, 0.146 mmol, 39%.)
