Sodium Hydroxide → 2-(4-Bromo-2-fluorophenyl)acetic acid

Participants

Reaction Steps

4-Bromo-2-fluoro-phenylacetamide (1.3 gm) was suspended in 100 ml of 30% NaOH, heating at reflux temperature for 24 hrs, cooled to room temperature, washed with DCM and ethyl acetate. The aqueous layer was acidified with conc. HCl, extracted with ethyl acetate, evaporated; the residue was crystallized from isopropanol-water to give needle crystals (0.5 gm, 38%) H1-NMR INOVA-500 (DMSO d6) 3.619(s, 2H), 7.316(t, J=8.0 Hz, 1H), 7.379(dd, J=8.0, 1.5 Hz, 1H), 7.516(dd, J=8.0, 1.5 Hz, 1H), 12.555(s, 1H).
