Reaction Steps

N-(3-fluoro-4-nitrophenyl)morpholine (6.01 g,26.59 mmol) and a catalytic amount of palladium on carbon(10%) were suspended in 100 mL methanol in a Parr flask. The reaction mixture was placed on the Parr Hydrogenator at 60 psi for 2 H. The reaction mixture was passed through a Celite pad and the filtrate was concentrated under reduced pressure to give 4.50 g of N-(3-fluoro-4-aminophenyl)morpholine an off-colored solid. 1HNMR(DMSO-d6) δ: 6.73 (t, 1 H, J=9.34), 6.28 (m, 2 H), 3.64 (bt, 4 H, J=4.58 Hz), 2.76 (bt, 4 H, J=4.58 Hz). ESI mass spectrum analysis m/z(relative intensity) 197 (M+H, 100). 19FNMR(DMSO-d6) δ: -124.455.
