Procedure

To a solution of 0.60 g (1.49 mM) of N-[2-(4-piperidyl)ethyl]-5-thia-1,8b-diazaacenaphthylene-4-carboxamide dihydrochloride and 1.0 ml (7.17 mM) of triethylamine in ethanol (6 ml) was added 0.27 ml (1.78 mM) of 3-phenyl-1-bromopropane at room temperature and the mixture was refluxed under nitrogen for 24 hours. The solvent was then distilled off under reduced pressure and the residue was diluted with water and extracted with chloroform. The organic layer was washed with saturated aqueous solution of sodium chloride, dried over MgSO4, and purified by column chromatography (methanol/ethyl acetate 30-50-80%) to provide the title compound.
