Ethyl-4-aminophenylacetate (20 g, 112 mmol) was dissolved in chloroform (300 ml) and treated with N-chlorosuccinimide (14.92 g, 112 mmol) and stirred for 15 minutes at room temperature under argon. Reaction mixture was washed with water, brine and dried over magnesium sulphate. Evaporated to a brown oil which was purified by chromatography on silica gel eluting with ethyl acetate (0-45%) in hexane to give the title compound as a orange oil (10.12 g, 47.4 mmol). LC/MS: Rt=2.59, [MH]+ 214.
