N-benzoylmethyl-piperidines

N,N,N',N'-tetrasubstituted-1,2-ethanediamine derivative compounds

Derivatives of piperazine having the general formula ##STR1## wherein R.sub.1 is benzhydryl or cinnamyl and R.sub.2 is selected from the group consisting of ##STR2## --(CH.sub.2).sub.3 --R.sub.8, --CH.sub.2 NHR.sub.9, --CH.sub.2 NH.sub.2 and --COR.sub.10 ; wherein R.sub.3 is hydrogen, chloromethyl, (4-benzhydryl-1-piperazinyl) methyl, 4-morpholinylmethyl or 1-piperidinylmethyl, R.sub.4 is hydrogen, chloromethyl or carbethoxy, R.sub.5 and R.sub.6 taken together are an oxygen atom or the radical --O--(CH.sub.2).sub.2 --O--, R.sub.7 is methyl, phenyl or 2-thienyl, R.sub.8 is 4-morpholinyl, 1-piperidinyl or 4-benzhydryl-1-piperazinyl, R.sub.9 is 2-oxo-1- (pyrrolidinyl) acetyl, 2-hydroxybenzoyl or 4-sulfamoylbenzoyl, R.sub.10 is 2-oxo-1-(pyrrolidinyl)methyl or 4-sulfamoylphenyl and X is oxygen or NH; as well as methods for making the same and their use in a pharmaceutical composition is proposed. The compounds have cardiovascular properties and increasing effects on cerebral flow.
