(4-bromo-2-fluorophenyl) acetate

Conditions: temp:150.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: AlCl3 (5.0 g, 38 mmol) was added in portions to 4-bromo-2-fluorophenyl acetate (5.8 g, 25 mmol). The mixture was heated at 150° C. for 3 h and then brought to ambient temperature. Water (ice-cold) was slowly added and then EtOAc. The resulting mixture was vigorously stirred and then the phases were separated and the water phase extracted with EtOAc. The combined organic phases were washed with brine, dried (Na2SO4) and evaporated to dryness to give the title compound (5.3 g). MS m/z (rel. intensity, 70 eV) 233 (M+, 55), 232 (M+, 56), 218 (98), 217 (bp), 161 (10). brought to ambient temperature the phases were separated the water phase extracted with EtOAc The combined organic phases were washed with brine dried (Na2SO4) evaporated to dryness

Conditions: temp:100.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 4-bromo-2-fluorophenol (5 g, 30 mmol) and acetic anhydride (13.4 g, 130 mmol) in pyridine (10.6 ml, 130 mmol) was heated at 100° C. for 3 h and then brought to ambient temperature and poured into water. HCl (1 N and 6 N) was added and the solution was extracted with EtOAc. The combined organic phases were washed with sodium bicarbonate (saturated, 3×50 ml), dried (Na2SO4) and evaporated to dryness to give the title compound (5.8 g).
