5,6-dihydro-4H-cyclopenta[b]thiophene-6-carboxylic acids represented by the formula: ##STR1## in which Ar is a phenyl or thienyl group, optionally substituted, or a furyl group; R is a lower alkyl radical, are useful as anti-inflammatory and analgesic medicines.

5,6-Dihydro-4H-cyclopenta(b)thiophene-6-carboxylic acids, preparation

Disclosed are 2-amino-5-phenyl-1,3-benzodiazepines of the formula ##STR1## wherein R.sub.1 and R.sub.2 are hydrogen, halogen, alkyl, or alkoxy; R.sub.2 being able to occupy any of the possible positions on the aromatic ring; R.sub.3 is hydrogen or alkyl; and R.sub.4 is hydrogen, alkyl, cycloalkyl, arylalkyl, heteroarylalkyl, dialkylaminoethyl, dialkylaminopropyl, (1-ethyl-2-pyrrolidino) methyl, dialkylamino, alkoxycarbonyl or cyano; or R.sub.3 and R.sub.4 form, with the adjacent nitrogen atom, a heterocycle having 5 to 7 side chains, optionally containing another heteroatom selected from oxygen, sulfur or nitrogen, this latter being able to be substituted by an alkyl group. The majority of the compounds are obtained by condensation of the corresponding 2-methylthio benzodiazepine hydroiodide with an appropriate amine. The compounds are useful as antidepressants.
