Versuchsvorschrift
10 Grams (0.268 mole) of the compound prepared under (A) were dissolved in 100 ml of anhydrous benzene and subsequently added with 3.02 ml (0.0269 mole) of 4-fluoro-phenylisocyanate, then the resulting solution was stirred on an oil bath at 30°-35° C. for 7 hours. After evaporating the solvent, the residue was taken up with anhydrous diethyl ether and the obtained white precipitate was recovered by filtration.
