Procedure

0.852 g (11.98 mmol) of pyrrolidine is added to a sealed tube comprising 0.060 g (0.29 mmol) of 4-(6-chloropyridin-3-yl)-1-azabicyclo[2.2.1]heptane obtained in stage 5.1 of Example 5. The mixture is heated at 130° C. for 3 hours, cooled to ambient temperature and diluted with 40 ml of toluene and the combined mixture is concentrated under reduced pressure. The residue thus obtained is diluted with 50 ml of dichloromethane and poured into 300 ml of a saturated aqueous sodium carbonate solution. The aqueous phase is extracted twice with 100 ml of dichloromethane, and the combined organic phases are dried over sodium sulfate and concentrated under reduced pressure. The residue is purified by chromatography on a column of silica gel, elution being carried out with a mixture of chloroform, methanol and aqueous ammonia in the proportions 85/15/1.5. 0.029 g of the expected product is obtained in the form of a brown powder.
