PROCEDURE

实验过程

As described under 11.3., 5.1 g (0.02 mol) of 9-hydroxyimino-3,6-dimethoxyfluorene are reacted at 0° C., in the presence of 3.0 g (0.03 mol) of triethylamine in 100 ml THF, with 5.6 g (0.022 mol) of 4-dodecylbenzenesulfonyl chloride. The crude product obtained after isolation is purified by flash chromatography on silica gel (eluant: petroleum ether/ethyl acetate 4:1). 5.8 g (51.3%) of 9-(4-dodecyl-phenylsulfonyloxyimino)-3,6-dimethoxyfluorene are obtained in the form of a viscous yellow oil. The UV spectrum (acetonitrile) of the substance shows absorption bands with a maximum at 315 nm (ε=21100) that extend to 443 nm. Elemental analysis: C33H41NO5S (563.76)
