実験手順
15 g (59 mmol) of (4-Hydroxyimino-cyclohexa-2,5-dienylidene)-(4-methoxyphenyl)-acetonitrile are dissolved in 200 ml of THF and cooled in an ice bath. After adding 12.4 ml (89 mmol) of triethylamine to the solution, 5.03 ml (65 mmol) of methanesulfonyl chloride are added dropwise, keeping the temperature below 5° C. The reaction mixture is gradually warmed to room temperature, and stirred for 1 hr. The reaction mixture is poured into 300 ml of water, and extracted with ethyl acetate. The organic phase is washed with hydrochloric acid solution, water, and sodium chloride solution. The organic phase is dried over MgSO4, the solvent is distilled off, and the residue is purified by recrystallization from ethyl acetate. 6.8 g (35%) of (4-Methylsulfonyloxyimino-cyclohexa-2,5-dienylidene)-(4-methoxyphenyl)-acetonitrile are obtained in the form of orange crystals having a melting point of 161-162l° C. (dec.).
