To a solution of (1S,5R)-1-[4-(trifluoromethyl)phenyl]-3-azabicyclo[3.1.0]hexane (P4, 1.00 g) in dry THF (5 mL), DIPEA (2.4 mL) and 1-bromo-3-chloropropane (3.7 mL) were added and the resulting mixture was heated at reflux for 3 hours. After cooling at room temperature it was diluted with EtOAc (30 mL) washed twice with a saturated solution of NH4Cl in water (20 mL) and once with a saturated aqueous NaHCO3 solution (20 mL), dried over anhydrous Na2SO4 and concentrated under reduced pressure. The crude product was purified by silica gel chromatography eluting with cyclohexane/EtOAc 7:3 to give the title compound as a colourless oil (1.26 g).
