Abstract

NEW MATERIAL:A 1-aroyl-3-halogenocyclohexene of formula I (Ar is aryl; X is halogen).
EXAMPLE: 3-Bromo-1-benzoylcyclohexene.
USE: A raw material of ketoprofen having excellent analgesic and antiphlogistic activities. Ketoprofen can be prepared from the compound in short steps.
PROCESS: The compound of formula I is prepared by halogenating, e.g. 1-aroylcyclohexene of formula II with a halogenating agent such as N-bromosuccinimide, pref. under light irradiation, or in the presence of a radical-generating agent such as benzoyl peroxide.
