    Abstract: A process for the production of compounds of formula I, ##STR1## wherein R.sub.1 is alkyl of 1 to 3 carbon atoms,R.sub.2 is hydrogen, fluorine, chlorine or bromine, andR.sub.3 is bromine, iodine, isobutyl, tert. butyl, cyclohexyl, cyclohexenyl; or phenyl, optionally substituted by fluorine, chlorine, bromine or alkoxy of 1 to 4 carbon atoms; or a radical of formula II, ##STR2## in which either R.sub.4 and R.sub.5 are the same or different and each signifies alkyl of 1 to 3 carbon atoms, orR.sub.4 and R.sub.5 together signify the radical --(CH.sub.2).sub.n --, in which n is 4 or 5, the radical --CH.sub.2 --CH.sub.2 --0--CH.sub.2 --CH.sub.2 --, the radical --CH.sub.2 --CH.dbd.CH--CH.sub.2 --, or the radical --CH.sub.2 --CH.sub.2 --N(R.sub.6)--CH.sub.2 --CH.sub.2 --, in which R.sub.6 is hydrogen or alkyl of 1 to 3 carbon atoms. Hydroxyketone and hydroxy imine intermediates are also disclosed.The compounds of formula I are known to exhibit anti-inflammatory activity.
