Reaction Steps
A mixture of 1.3 g of the compound obtained in step C of EXAMPLE 71 and 1.1 g of 4-(piperid-1-yl)piperidine in 4 ml of DMF is heated at 70° C. for 4 hours. After cooling to RT, the reaction mixture is poured into iced water and extracted with AcOEt, the organic phase is washed with 1 N 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. M.p.=270° C. (dec.).
