Procedure

A mixture of compound 15 (0.005 mol), N-[2-(3,4-dichlorophenyl)-4-[(methylsulfonyl)oxy]butyl]-N-methyl benzamide (0.0055 mol) and NaHCO3 (0.0055 mol) in ethanol (50 ml) was stirred and refluxed for 6 hours. The solvent was evaporated, the residue was taken up in water and extracted with CH2Cl2. The organic layer was separated, dried, filtered and the solvent was evaporated. The residue was purified over silica gel on a glass filter (eluent: CH2Cl2/CH3OH 100/0, 99/1, 98/2 and 97/3). The pure fractions were collected and the solvent was evaporated. The residue was converted into the fumaric acid salt (1:2) with ethanol. The precipitate was filtered off and dried, yielding 1.42 g (27%) of (±)-cis-N-[4-[4-[1-[3,5-bis(trifluoromethyl)benzoyl]-2-(phenylmethyl)-4-piperidinyl]-1-piperazinyl]-2-(3,4-dichlorophenyl) butyl]-N-Methylbenzamide (E)-2-butenedioate (1:2) (compound 93).
