Ethanol → Ethyl 2-(2-bromophenyl)acetate

Participants

Reaction Steps

To a cooled solution of 730.0 g of o-bromophenylacetonitrile in 2.9 l of absolute ethanol is added, dropwise, while stirring, 740 ml of concentrated sulphuric acid. The addition requires about 2 hours. The reaction mixture is heated under reflux for 9 hours, poured into ice water, and extracted with 2.5 l of ether. The ether extracts are washed, dried, and concentrated. The residue is distilled to give 780.0 g of ethyl o-bromophenylacetate, bp. about 115°-117° (4mm), nD26 1,5434.
