Versuchsvorschrift
20 g 2-(N-isopropyl-N-carbomethoxyamino)-4-methyl-4'-fluoro-2,5-dihydrobenzophenone and 100 g manganese dioxide in 200 ml chloroform are stirred 4 hours under reflux. The reaction mixture is cooled, filtered and evaporated in vacuo. The residue is recrystallised from hexane to obtain the heading compound, m.p. 92°-94° C.
