Morpholino containing indane acetic acid esters

Abstract

The present invention relates to certain indane derivatives of general formula ##STR1## in which: X represents a hydrogen or halogen atom; R.sub.1 and R.sub.2, which may be identical or different, each represents a hydrogen atom, an alkyl group containing 1 to 5 carbon atoms or a cycloalkyl group containing 3 to 7 carbon atoms; R.sub.3 represents a hydrogen atom or an alkyl group containing 1 to 5 carbon atoms; and Y represents --CH.sub.2 OH or a group of formula --COOR.sub.4 in which R.sub.4 represents a hydrogen atom, 1/v(M) where M is a metal of valency v, or a group of formula --(CH.sub.2).sub.n --NR.sub.5 R.sub.6 wherein n is an integer of 1 to 5 and R.sub.5 and R.sub.6, which may be identical or different, each represents a hydrogen atom, an alkyl group containing 1 to 5 carbon atoms, a cycloalkyl group containing 3 to 7 carbon atoms, an aryl group or an aralkyl group, or R.sub.5 and R.sub.6, together with the nitrogen atom to which they are bonded, form an N-heterocyclic group with 5 to 7 ring members, which heterocyclic group optionally contains a second hetero-atom, and their pharmaceutically acceptable addition salts, and to processes for their preparation. The compounds of formula (I) and their salts are useful for the treatment of inflammations, algias, rheumatisms or pain syndromes in animals.
