Participants

Reaction Steps

The obtained ethyl 1-(2-chloro-4-fluoro-5-amino-phenoxy)cyclopropanecarboxylate (1 equivalent) and dimethylaniline (1 equivalent) are added to THF and ethyl chloroformate (1 equivalent) is gradually added in drops thereto. After completion of addition, to the reaction solution is added aqueous diluted hydrochloric acid and the mixture is extracted with ethyl acetate. After concentrating the organic layer, the residue is subjected to chromatography to give ethyl 1-(2-chloro-4-fluoro-5-ethoxycarbonylaminophenoxy)cyclo-propanecarboxylate.
