ABSTRACT:
A compound of the formula ##STR1## R.sub.1 is hydrogen, alkali metal, alkaline earth metal, lower alkyl, pivaloyloxymethyl or phthalidyl;
R.sub.2, R.sub.3, R.sub.4 and R.sub.5 are the same or different and are hydrogen, halogen, lower alkoxy or ##STR2## wherein R.sub.6 and R.sub.7 are lower alkyl or R.sub.6 and R.sub.7 together with the nitrogen atom to which they are attached form a five- to seven-membered unsubstituted or substituted heterocyclic ring containing said nitrogen atom as the sole hetero atom or containing nitrogen, sulfur or oxygen as additional hetereo atoms;
A is a saturated or unsaturated hydrocarbon chain of one to five carbon atoms, unsubstituted or substituted by lower alkyl; lower alkoxy; lower alkylthio; hydroxy; halogen; lower alkyl substituted by halogen, amino, loweralkoxycarbonyl, carboxy, lower-alkoxy, loweralkylthio, loweracyloxy or hydroxy; loweralkylamino; carboxy; nitro; cyano; carbonyl; imino; or by substituted or unsubstituted phenyl, phenylthio, phenylamino or phenoxy; and
R.sub.2 and R.sub.3 or R.sub.3 and R.sub.4 or R.sub.4 and R.sub.5 together may be alkylenedioxy of 1 to 5 carbon atoms which form a ring with the carbon atoms to which they are attached; or a pharmaceutically acceptable salt thereof.
