This compound is prepared by the procedure described in step D of EXAMPLE 1 from 1.32 g of 4-hydroxy-4-phenylpiperidine, 1.55 g of the compound obtained in step C of EXAMPLE 1 and 0.56 g of potassium iodide in 10 ml of DMF. The residue is chromatographed on silica H using DCM and then a DCM/MeOH mixture (96/4; v/v) as the eluent. The product obtained is dissolved in DCM and acidified to pH 1 by the addition of a saturated solution of gaseous HCl in ether and the solvents are evaporated off under vacuum to give 0.72 g of the expected compound after crystallization from ether. M.p.=172° C.
