2-Benzylaminomethyl-1,2,3,4-tetrahydronaphthalene (XXXIV) (2.8 g), N,N-diisopropyl-N-ethylamine (1.44 g) and 4'-(2-bromoacetyl)methanesulfonanilide (Temple, D. L. et al., J. Med. Chem., 19(5), 626-633 (1976)) (3.27 g) were dissolved in acetone (40 ml) and stirred 18 hours at ambient temperature. The solvent was evaporated and the residue was dissolved in CH2Cl2, which was washed with H2O, dried (MgSO4) and evaporated. The HCl salt was made by dissolving the residue in MeOH/concentrated HCl, concentrating, and triturating the residue with 2-PrOH and ether. The solid product, 4'-[1-oxo-2-(N-benzyl-N-((1,2,3,4-tetrahydro-2-naphthyl)methyl)-amino)ethyl]methanesulfonanilide.HCl (XXXIII.HCl), 3 g, had NMR and mass spectra consistent with the structure indicated. It was used without further purification.
