Abstract
The invention relates to 2,3-dihydrobenzofuran derivatives of the general formula: ##STR1## in which: each of X.sub.1 and X.sub.2, which are identical or different, represents a hydrogen or halogen atom or an alkoxy radical containing from 1 to 4 carbon atoms, PA1 X.sub.3 represents a hydrogen atom or an alkyl radical having from 1 to 4 carbon atoms, PA1 Y represents a hydrogen atom or a hydroxy radical, each of R.sub.1 and R.sub.2, which are identical or different, represents an alkyl radical having from 1 to 4 carbon atoms, PA1 or R.sub.1 represents a methyl radical and R.sub.2 represents a phenylalkyl grouping or a 2-indanyl grouping, each of which may be substituted or unsubstituted, PA1 or R.sub.1 and R.sub.2 together form, with the nitrogen atom to which they are attached, a piperazinyl radical, a tetrahydroisoquinolyl radical, a morpholinyl radical or a tetrahydrothienopyridinyl radical.
