실험 절차

23.8 g of fluorodichloromethanesulphenyl chloride in 100 ml of acetic acid ethyl ester is added dropwise within 20 minutes at -10° C, with vigorous stirring, to a suspension of 22.5 g of 3-(3'-chloro-4'-methylphenyl)-imidazolidine-2,4-dione in 400 ml of acetic acid ethyl ester, and after one hour there is also added dropwise, at 0° C in the course of 10 minutes, 14.2 g of triethylamine in 100 ml of acetic acid ethyl ester; the cooling bath is subsequently removed and stirring is continued for 3 hours at room temperature. The triethylamine hydrochloride that has precipitated is filtered off and then washed with 100 ml of acetic acid ethyl ester; the solvent is evaporated off in vacuo to obtain, after recrystallisation in methanol, Compound No. 1 which melts at 166° - 167° C.
