160 °C

Copper lining powder (75g) was added portionwise over 30 minutes to a stirred mixture of 1-ethyl-4-iodobenzene (34.8g, 0.15 mole) and 2-bromo-1-nitrobenzene (30.3g, 0.15 mole) in nitrobenzene (250 ml) at 160°. After stirring for a further 3 hours at 160° C the solution was cooled, diluted with methylene chloride and filtered. Methylene chloride was distilled, nitrobenzene was steam-distilled, and the product was isolated in ether, and distilled to give 4-ethyl-2-nitrobiphenyl, b.p. 120°-130° C/0.1mm.
