Abstract
Abstract The syntheses of ethyl 2-[4-(3-fluoro-2-quinoxalinyloxy)phenoxy]propanoate ( 1d ), a new fluoro analogue of the herbicide quizalofopethyl, from 2,3-dichloroquinoxaline ( 3 ) and of ethyl 2-[4-(6-chloro-3,4-dihydro-3-oxoquinoxalinyl-2-oxy)phenoxy]propanoate ( 9 ) from ethyl 2-[4-(3,6-dichloro-2-quinoxalinyloxy)phenoxy]propanoate ( 2b ) via nucleophilic substitution with cesium fluoride coupled with 18-crown-6 are described.
