Mode opératoire

To a solution of (1S,5R)-1-[2-fluoro-4-(trifluoromethyl)phenyl]-3-azabicyclo[3.1.0]hexane (P13, 426 mg) in dry tetrahydrofuran (9 mL), triethylamine (0.79 mL) and 1-bromo-3-chloropropane (0.37 mL) were added and the resulting mixture was refluxed for 16 hours. After cooling at room temperature it was concentrated in vacuo, diluted with ethyl acetate, washed with a saturated solution of NaHCO3 in water and brine, dried over anhydrous Na2SO4 and concentrated under reduced pressure. The crude product was purified by chromatography (silica gel) eluting with cyclohexane/EtOAc 8:2 to give the title compound as yellow oil (582 mg).
