実験手順

A mixture of 0.55 g of 4-piperidinopiperidine, 1.3 g of the compound obtained in step B of EXAMPLE 1 and 1.14 g of K2CO3 in 10 ml of a DMF/acetonitrile mixture (50/50; v/v) is heated at 100° C. for 3 hours. The reaction mixture is poured into water and extracted with AcOEt, the organic phase is washed twice with water and with saturated NaCl solution and 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 (98/2; v/v) as the eluent. The product obtained is dissolved in AcOEt, a stream of HCl gas is bubbled into the solution until the pH is 1, and ether is added until precipitation occurs. This gives 0.53 g of the expected product after filtration and drying, m.p.=265° C. (dec.).
