| abstract |
ABSTRACT OF THE DISCLOSURE New flavone derivatives to be used as analeptics having the formula (I) wherein R1 and R2 are both methyl or ethyl, or taken together with the nitrogen atom to which they are attached represent a mononuclear 5- or 6-membered heterocyclic ring which may contain an oxygen atom as further hetero atom; R3 and R4 are hydrogen or methyl, provided that at least one of them is hydrogen, and pro-cess for the preparation thereof starting from resorcinol and phenylacetonitrile or a phenylacetonitrile derivative. |
