Procedure

A mixture of 0.86 g of the compound obtained in step C of EXAMPLE 26 and 0.7 g of 4-(piperid-1-yl)piperidine in 3 ml of DMF is heated at 70° C. for 4 hours 30 minutes. After cooling to RT, the reaction mixture is poured into water and extracted with AcOEt, the organic phase is washed with 1N NaOH solution and with saturated NaCl solution and dried over Na2SO4 and the solvent is evaporated off under vacuum. The residue is chromatographed on silica H using DCM and then a DCM/MeOH mixture (90/10; v/v) as the eluent. The product obtained is taken up with a saturated solution of hydrochloric acid in ether and the precipitate formed is wrung to give 0.49 g of the expected product.
