Yield: 983.2 %

Procedure:
6.5 g of (2,3-dioxo-2,3-dihydro-1H-indol-5-yl)cyclopropanecarboxylic acid are dissolved in 100 ml of ethanol, and 500 mg of toluene-4-sulfonic acid monohydrate are added. The mixture is heated at 80° C. for 1 h and subsequently evaporated in vacuo. The residue is taken up in 100 ml of water and 100 ml of ethyl acetate and stirred at 60° C. for a further 12 h. The mixture is neutralised using sodium hydrogencarbonate, and the organic phase is separated off. The aqueous phase is washed a further twice with 100 ml of ethyl acetate each time. The combined organic phases are dried over sodium sulfate, filtered and evaporated to dryness in vacuo, giving 6.7 g (92%) of ethyl 1-(2,3-dioxoindolin-5-yl)cyclopropanecarboxylate; LC-MS retention time: 1.30 min.

Procedure:
A suspension of 17.2 g of ethyl 4-hydroxy-3-methoxy-5-nitrophenylglyoxylate in 100 ml of dry acetonitrile and 100 ml of dry toluene is treated with 10.53 g of sodium iodide and 11.9 g of silicon tetrachloride and heated under reflux for 47 hours. The reaction mixture is then evaporated and the residue is distilled six times with 200 ml of toluene each time. The residue obtained is partitioned between water and ether and filtered through a filter aid of diatomaceous earth. The ethereal phase is washed four times with saturated sodium chloride solution, dried over sodium sulfate, filtered and evaporated. The oily residue is treated three times with ether and active carbon. There is obtained ethyl 3,4-dihydroxy-5-nitrophenylglyoxylate of m.p. 77°-79° (from ether/n-hexane).
