Versuchsvorschrift

2 g 5-tert-butyl-2-methoxy-1,3-dinitro-benzene are dissolved in 20 ml ethanol and combined with 2 ml of water and 100 mg of 10% palladium on charcoal. The mixture is refluxed, 1.9 ml of 4-methyl-1-cyclohexene are added and the mixture is refluxed for a further 2 hours. Then a further 1.0 ml of 4-methyl-1-cyclohexene are added dropwise and the mixture is refluxed for a further 16 hours. Then it is cooled to ambient temperature, the solvents are eliminated in vacuo and the residue is taken up in ethyl acetate. The mixture is washed with saturated aqueous sodium hydrogen carbonate solution, water, saturated aqueous sodium chloride solution and dried with sodium sulphate. The solvent is eliminated in vacuo and the product thus obtained is further reacted directly.
