Procedure
A solution of 40 mg (0.094 mmol) of N-[4-(5-Dimethylamino-pent-1-ynyl)-phenyl]-N-methyl-4-trifluoromethyl-benzenesulfonamide in 3 ml MeOH/0.3 ml dioxane was treated with 0.094 ml 1N AcOH in MeOH followed by 4 mg Pd/C10%, type EION (under argon) and then hydrogenated (1 atm) for 3 h. The reaction mixture was filtered (Celite) and extracted with aqueous sat. NaHCO3/Et2O (3×). The organic phases were washed with aqueous 10% NaCl solution, dried (Na2SO4) and evaporated to yield 27 mg (66%) of N-[4-(5-Dimethylamino-pentyl)-phenyl]-N-methyl-4-trifluoromethyl-benzenesulfonamide, MS: 429 (MH+).
