Abstract

1379005 Dihydropyridines BAYER AG 6 March 1973 [6 March 1972 12 Sept 1972] 10759/73 Heading C2C The invention comprises novel compounds of the tautomeric formulae in which R is a saturated or unsaturated, straight-chain, branched or cyclic hydrocarbon radical, or an aryl radical optionally carrying 1, 2 or 3 identical or different substitutents selected from aryl, alkyl, alkoxy, azido, halogen, nitro, cyano, trifluoromethyl, carbalkoxy and -SO n -Alkyl (in which n = 0, 1 or 2) radicals, or a naphthyl, quinolyl, isoquinolyl, pyridyl, pyrimidyl, thenyl, furyl or pyrryl radical optionally carrying at least one substituent selected from alkyl, alkoxy and halogen radicals; and R<SP>1</SP> and R<SP>2</SP> which can be the same or different, are each a radical -OR<SP>1</SP> in which R<SP>1</SP> is a straight-chain, branched or cyclic, saturated or unsaturated aliphatic hydrocarbon radical the carbon chain of which may be interrupted by 1 or 2 oxygen atoms, or an amino, alkylamino, or dialkylamino group. They are made by reacting an amidine of formula with RCHO or with an ylidene cyanoacetic acid derivative of formula R<SP>1</SP>OC-C(.CN)(:CHR). Pharmaceutical preparations especially useful as coronary and anti-hypertensive agents contain the novel compounds as active ingredients; standard administration forms are described. [GB1379005A]
