4-[4-(3-Pyrrolidin-1-yl-propoxy)-phenyl]-tetrahydro-pyran-4-carbonitrile (0.5 g, 3.1 mmol), ethylenediamine (1.5 mL, 22 mmol), copper (II) acetate (0.07 g, 0.3 mmol) and N-methylpyrrolidinone (1.5 mL) were combined and subjected to microwave (Smith Personal Synthesiser) irradiation at 220° C. for 1 hour. The reaction mixture was concentrated in vacuo to provide a brown oil. This was columned by flash chromatography on silica gel eluting with dichlromethane:methanol:ammonia (94:6:0.6 to 85:15:1.5) to provide the title compound (0.157 g, 31%) as a yellow oil. LRMS ESI+ m/z 358 [MH]+.
