Mode opératoire

This compound is prepared by the procedure described in EXAMPLE 4, starting from 2.5 g of 4-benzyl-4-cyanopiperidine, 5 g of the compound obtained in step B of EXAMPLE 1, 3.7 g of K2CO3 and 50 ml of DMF. The product obtained is chromatographed on silica H using DCM and then a DCM/MeOH mixture (97/3; v/v) as the eluent. The product obtained is taken up with ethereal hydrogen chloride and the solvent is evaporated off under vacuum to give 2.8 g of the expected product after crystallization from iso ether.
