Reaction Conditions

Reaction Steps

4-Aminophenylacetic acid (100 g) was suspended in methanol (1000 ml) and gaseous hydrogen chloride was passed through until the mixture was saturated. The mixture was heated at 50° C. for 2 hours and was then allowed to cool to room temperature. The solvent was evaporated in vacuo and the residue was taken up in aqueous sodium bicarbonate solution and extracted with ethyl acetate. The organic extract was washed with brine, dried over anhydrous magnesium sulfate, filtered and the filtrate evaporated in vacuo to afford methyl 4-aminophenylacetate as a pale brown liquid.
