Procedure

A solution of 1-(4-chloro-butyl)-4-(6-methyl-pyridin-2-yl)-1H-pyrimidin-2-one (Prep17, 48 mg, 0.17 mmol), (1S,5R)-1-(4-trifluoromethyl-phenyl)-3-aza-bicyclo[3.1.0]hexane (Prep4, 38 mg, 0.17 mmol), KI (2 mg) and DIPEA (66 mg, 0.51 mmol) in absolute EtOH (2 ml) was placed in a microwave oven and irradiated at 125° C. for 13 hours. The solvent was removed under vacuum and the residue was redissolved in DCM and filtered. The filtrate was stirred in the presence of PS-isocyanate (350 mg) for 3 hours. The mixture was filtered and the solvent removed under vacuum. The crude was purified by flash chromatography with DCM-MeOH—NH4OH (99-1-0.1) to give the title compound (17 mg, 4% yield) as a free base.
