α-chloroacetylchloride (10.1 g, 0.128 mole) was added dropwise under stirring at room temperature to the 2-aminohydroquinone (4.16 g, 0.128 mole) in dry acetone (400 ml) and diethanolamine (2.04 ml, 0.128 mole). The reaction mixture was poured into water and hydrochloride acid (2,000 ml, pH 1), then extracted with ethylacetate (500 ml). The solvent was evaporated to dryness and the solid residue (4.20 g, 80%) was used without any further purification. The structure of the 2-(α-chloroacetamido)-hydroquinone was confirmed by NMR analysis.
