Procedure
A mixture of 2-nitrophenylacetic acid (300 g, 1.66 mol) and sulfuric acid (d=1.84 g/ml, 6 ml) in methanol (61) was heated under reflux for 21 h. The solvent was removed in vacuo and the residue dissolved in dichloromethane (21). The dichloromethane solution was then washed with saturated aqueous sodium carbonate solution (600 ml), brine (500 ml), dried (MgSO4), filtered and then evaporated in vacuo.
