Abstract

1504840 1 - Carbamoyl - 3 - (3,5 - dichlorophenyl)hydantoins PHILAGRO 8 Sept 1976 11 Sept 1975] 37227/76 Heading C2C Compounds (I) where R is C 1-4 alkyl or C 2-4 alkenyl are made by cyclizing compounds (III), suitably at up to 100‹ C. with an organic acid anhydride. 2 - [3 - (3,5 - Dichlorophenyl) - 1 - isopropylcarbamoylureido]acetic acid is made by reacting glycine with isopropyl isocyanate, cyclizing the resulting 2-(3-isopropylureido)acetic acid, reacting the formed 3-isopropylhydantoin with 3,5 - dichlorophenyl isocyanate and treating the resulting 1 - (3,5 - dichlorophenyl)carbamoyl- 3-isopropylhydantoin with NaOH.
