There are described compounds of formula I, ##STR1## in which R.sub.1 is phenyl substituted by halogen, alkoxy, alkyl, carboxy-alkyl, --NR.sub.4 R.sub.5, carboxy or alkoxy carbonyl, R.sub.3 is hydrogen, alkyl, mono- or di-carboxy alkyl, halo, alkoxy, phenyl, halo-phenyl, hydroxy, phenoxy, thiol, thioalkoxy, thiophenoxy, --NR.sub.4 R.sub.5, cyano, --COOH, carboxyureido, --CF.sub.3, --COR.sub.6, hydroxyalkyl, aminoalkyl, or alkoxy substituted by NR.sub.4 R.sub.5, ring A is a benzene or a pyridine ring which optionally carries up to 4 substituents R.sub.3, which may be the same or different, R.sub.4 and R.sub.5, which may be the same or different, each represent hydrogen, phenyl, halophenyl or alkyl, the alkyl optionally being substituted by alkoxy or by a mono- or di-alkyl or unsubstituted amino group; or R.sub.4 and R.sub.5, together with the nitrogen atom to which they are attached, form a piperidine, morpholine or an optionally alkyl substituted piperazine ring, and R.sub.6 is hydrogen or alkyl, provided that (i) when R.sub.1 is phenyl substituted by chlorine or bromine, ring A is not a benzene ring substituted by chlorine or bromine, or (ii) when R.sub.1 is phenyl substituted by methoxy R.sub.3 is not phenyl, and pharmaceutically acceptable salts, esters and amides thereof. There are also described methods for making the compounds and pharmaceutical, e.g. anti-inflammatory, compositions containing the compounds.
