Reaction Steps

A solution of 10 g (58 mmol) 5-chloro-2-nitroaniline in 250 ml dry tetrahydrofuran was added 8.5 ml (62 mmol) dry triethylamine. A solution of 7.0 ml (62.7 mmol) ethoxalylchloride in 50 ml dry tetrahydrofuran was added dropwise Stirring was continued at 25° C. for 20 h. The reaction mixture was filtered and evaporated in vacuo. The residue was stirred with ethanol to give 9.0 g (57%) 4-chloro-2-ethoxalylamino-1-nitrobenzene. M.p. 105.1° C.
