반응 단계
101 g of triethylamine are added to a suspension of 263 g of 2-[3-(3,5-dichlorophenyl)-ureido]-acetic acid in 2,000 cm3 of chlorobenzene and 300 g of isopropyl isocyanate, which has been heated to 50° C, and the mixture is stirred for 4 hours at 80°-90°. After cooling, the reaction mixture is stirred for 30 minutes with 500 cm3 of a 7% strength (weight/volume) aqueous solution of hydrochloric acid. The organic solution is decanted, dried and concentrated under reduced pressure. 332 g of 1-isopropylcarbamoyl-3-(3,5-dichlorophenyl)-hydantoin melting at 130° C are thus obtained.
