Procedure

4-(3-Fluoro-4-nitrophenyl)morpholine: A solution of 2,4-difluoronitrobenzene (10.0 mL, 91 mmol) and morpholine (17.4 mL, 200 mmol) in THF (100 mL) was stirred at RT under nitrogen for 2 h. The solvent was removed and the residue was partitioned between EtOAc and water. The organic layer was washed brine, dried over MgSO4, and concentrated. The resulting solid was purified by SiO2 chromatography with 20-50% EtOAc in hexane to give 4-fluoro-2-morpholinonitrobenzene (18.1 g) and 55a (1.81 g, 8% yield); [M+H]+=227.10.
