Reaction Conditions

Reaction Steps

Treat a −35° C. solution of fuming nitric acid (32.3 mL, 723 mmol) with 4-fluorophenylacetone (1.756 ml, 13.14 mmol) and stir at −35° C. for 1 h. Pour the mixture onto ice, extract with DCM (2×), dry the combined organics over MgSO4, concentrate to dryness and purify via silica gel chromatography (EtOAc/Hex) to afford the title compound (1.07 g, 41%). 1H NMR (400 MHz, DMSO-d6): δ 7.97 (dd, J=7.4, 2.2 Hz, 1H), 7.58 (ddd, J=8.6, 4.6, 2.2 Hz, 1H), 7.52 (dd, J=11.3, 8.6 Hz, 1H), 3.95 (s, 2H), 2.17 (s, 3H).
