Methanol → Methyl alpha-bromo-2-chlorophenylacetate

Participants

Reaction Steps

α-Bromo-2-chlorophenyl acetic acid (350.0 gm) was dissolved in methanol (1.18 Liter) and concentrated sulphuric acid (53.20 gm) was added. The reaction mixture was refluxed for 4 hours. After completion of the reaction, the reaction mixture was distilled out to get a syrupy mass. To the residual mass, water (560 ml) was added and the product was extracted into chloroform (560 ml). The chloroform layer was separated and was treated with 10% aqueous sodium bicarbonate solution (1.12 Litre). The chloroform extract was finally washed with water and chloroform was distilled out to get a syrupy mass to get the titled compound.
