4-[4-(2-Fluoro-phenyl)-2-oxo-2H-pyrimidin-1-yl]-butyraldehyde (Prep41, 50 mg, 0.19 mmol) was dissolved in DCE (5.5 ml). The resulting solution was cooled at 0° C. and then (1S,5R)-1-(4-trifluoromethyl-phenyl)-3-aza-bicyclo[3.1.0]hexane (Prep4, 53 mg, 0.23 mmol), AcOH (13 μl) and NaBH(AcO)3 (45 mg, 0.21 mmol) were added. The mixture was stirred for 10 minutes at 0° C. 1N NaOHaq was added and the product was extracted with DCM. The organic phase was dried (Na2SO4) and evaporated. The crude was purified by flash chromatography with DCM-MeOH—NH4OH (20-0.2-0.2) to give 52 mg of the title compound (58% yield) as a free base.
