Reaktionsschritte

To a solution of ethyl 2-(p-tolylamino)acetate (1.69 mmol) in methanol/water (20 ml/20 ml) was added the 2,3 dichloro-5,6-dicyanobenzoquinone (2.87 mmol) and the mixture was stirred for 4 hours at room temperature. The residue was chromatographed on a silica gel column (dichloromethane/ethyl acetate 8/2 as eluent) to give 88 mg of ethyl 2-(4-formylphenylamino)acetate. (yield 25%). MS (ESI): m/z 208.0 [M+H]+
