Benzyl Bromide → 4-Benzyloxy-2-fluoro-1-nitrobenzene

Participants

Reaction Steps

3-Fluoro-4-nitro-phenol (10 g, 0.064 mol) was reacted with benzyl bromide (8.3 ml, 0.070 mol), cesium carbonate (22.7 g, 0.07 mol), and tetrabutyl ammonium iodide (0.05 g) in N,N-dimethylformamide (100 mL) at 25° C. for 18 hr. The reaction mixture was poured into distilled water (500 mL) and stirred for 10 minutes. The reaction mixture was extracted with ethyl acetate (3×200 mL). The combined organic extracts were washed with brine, dried over anhydrous sodium sulfate, filtered and solvent removed under reduced pressure to give the title compound as a light yellow solid (15 g). 1H NMR (300 MHz, DMSO-d6) δ ppm 5.27 (s, 2 H) 7.06 (dd, J=9.56, 2.57 Hz, 1 H) 7.29 (dd, J=13.60, 2.57 Hz, 1 H) 7.44 (m, 5 H) 8.17 (t, J=9.19 Hz, 1 H). ESI m/z (M+H)+: 248
