A solution of 19.4 parts of 2,6-diethyl-4-nitroaniline in 40 parts by volume of concentrated hydrochloric acid is diluted with 80 parts of water and added to 100 parts of ice. A solution of 7 parts of sodium nitrite in 15 parts of water is added and the filtered diazonium solution treated with 150 parts by volume of 50% hypophosphorous acid and kept cold for 24 hours. The 3,5-diethylnitrobenzene which separates is extracted with ether and distilled, b.p. 190°/20mm.
