Abstract
NEW MATERIAL:A compound of formula I [Ar is aryl; R1 is H or lower alkyl; R2 and R3 are H, cyano, or -CO2R4 (R4 is lower alkyl); X1 and X2 are H or halogen].
EXAMPLE: Dimethyl 3-benzoyl-2-cyclohexen-1-ylmalonate.
USE: Raw material for the preparation of ketoprofen having lenitive and anti-inflammatory activities and its analogs.
PROCESS: 1-Aroylcyclohexene of formula II is halogenated with a halogenating agent, e.g. bromine, in a solvent at room temp. W reflux temp. of the solvent to give 1-aroyl-3-halogenocyclohexene of formula III. The compound obtained is made to react with a compound of formula IV preferably in a solvent at room temp. W reflux temp. of the solvent in the presence of a base, e.g. NaH, to afford a compound of formula I wherein both X1 and X2 are H.
