Participants

Reaction Steps

To a clean, dry 100 mL round bottom flask is added methyl 3-hydroxy-5-nitrobenzoate (240a, 0.4 g, 2 mmole, 1 eq), orthofluorobenzyl bromide (0.57 g, 3 mmole, 1.5 eq), potassium carbonate (0.56 g, 4 mmole, 2 eq), and DMF (3 mL). The reaction mixture was stirred at room temperature for 18 h and quenched with water and ethyl acetate. The product was extracted into the organic layer, dried over magnesium sulfate, filtered and evaporated. A white solid was obtained (0.49 g, 80% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 8.41 (s, 1H), 8.09 (s, 1H), 8.00 (s, 1H), 7.59 (dt, 1H, J=1.8, 8.0 Hz), 7.42 (m, 1H), 7.24 (dt, 1H, J=1.0, 8.0 Hz), 7.22 (dt, 1H, J=1.3, 8.0 Hz), 5.33 (s, 2H), 3.98 (s, 3H). Calc'd for C15H12FNO5; m/z (M+H+)=306; found 306.
