PROCEDURE

实验过程

A mixture of 4-benzyl-4-(pyrrolidin-1-ylcarbonyl)piperidine p-toluene-sulfonate, 0.65 g of the compound obtained in step B of EXAMPLE 1 and 0.7 g of K2CO3 in 6 ml of DMF is heated at 80° C. for 3 hours. The reaction mixture is poured into iced water and the precipitate formed is filtered off and washed with water. The precipitate is dissolved in AcOEt, the organic phase is dried over MgSO4 and the solvent is evaporated off under vacuum. The residue is chromatographed on silica H using DCM and then a DCM/MeOH mixture (95/5; v/v) as the eluent. The product obtained is taken up with ethereal hydrogen chloride and the precipitate formed is filtered off to give 0.56 g of the expected product.
