Versuchsvorschrift
A mixture of 15 g (57.7 millimoles) of 3-bromomethyl-6-nitro-benzoic acid, 15.17 g (57.7 millimoles) of triphenyl phosphine and 70 ml anhydrous toluene is refluxed for 2 hours. The precipitated product is filtered off, washed with ether and dried. Thus 21.15 g of the title compound are obtained, yield 71%.
