Procedimiento

200 mg (0.97 mmol) of 1-azabicyclo[2.2.2]oct-3-ylacetic acid hydrochloride are heated under reflux in 2 ml (27.42 mol) of thionyl chloride for 2 h. The mixture is then freed of excess thionyl chloride in vacuo, and the residue is taken up in 4 ml of DMF. 0.54 ml (3.89 mmol) of triethylamine, 5.9.4 mg (0.4 mmol) of DMAP and 183.0 mg (0.97 mmol) of 8-nitro-2-naphthylamine are added to this solution. After reaction overnight and purification by preparative. HPLC, the resulting product fractions are mixed With 1 M hydrochloric acid and concentrated in vacuo. Recrystallization of the residue from isopropanol and drying under high vacuum result in 59 mg (15% of theory) of the title compound.
