Versuchsvorschrift

A solution of 3-iodophenol (3 g, 13.6 mmol), acetyl chloride (2.9 ml, 40.9 mmol) and potassium carbonate (9.42 g, 68.2 mmol) in N,N-dimethylformamide (75 ml) was stirred for 16 h at room temperature. The mixture was partitioned between water and ethyl acetate. The organic layer was washed with 1N NaOH, dried over magnesium sulfate, and evaporated under vacuum. The crude product was chromatographed over silica gel, eluting with 20% ethyl acetate/hexanes to yield 2.3 g (65%) of 3-iodophenyl acetate.
