실험 절차

22.5 ml of triethylamine and then 22 g of the 3-(2-hydroxyethyl)-3-(3,4-dichlorophenyl)piperidine (-) prepared above according to PREPARATION III (f) are added to a solution of 16 g of 3-isopropoxyphenylacetic acid in 500 ml of CH2Cl2. The mixture is cooled to 0° C., 42.6 g of BOP are then added and the reaction mixture is allowed to warm up to room temperature. After 30 minutes, the mixture is concentrated under vacuum and the residue is taken up in ether and washed successively with water, a dilute solution of NaOH, a saturated solution of NaCl, a dilute solution of HCl, a saturated solution of NaCl and a solution of NaHCO3. The ether phase is dried over MgSO4, filtered and concentrated under vacuum to give 36 g of optically pure product.
