Reaktionsschritte
A mixture containing 6.5 g of 4-methyl-2'-nitrobiphenyl, 5.42 g of NBS, 118 mg of azo-bis-isobutyronitrile and 500 ml of carbon tetrachloride is refluxed for 5 hours. It is cooled to 0° C. and filtered and the filtrate is concentrated to give 9 g of an oily product, which is used as such in the next step.
