摘要:
A 3-[4-benzoylalkyl)piperazin-1-yl]sydnonimine compound represented by the following formula wherein R represents a hydrogen atom or an alkyl group having 1 to 8 carbon atoms, and n represents zero or an integer of 1 to 10, and its acid addition salt. The above sydnonimine compounds are useful for the treatment of troubles of the circulatory system and can be produced by contacting a 4-(benzoylalkyl)-1-(N-nitrosocyanomethylamino)piperazine represented by the following formula I wherein R and n are as defined, with an acid.

摘要:
An N-acyl-3-[4-(benzoylalkyl)piperazin-1-yl]-sydnonimine compound represented by the following formula wherein R' represents a hydrogen atom or an alkyl group having 1 to 8 carbon atoms, R 2 represents a lower alkyl group, a lower alkoxy group or a phenyl group, and n represents zero or an integer of 1 to 10, and its acid addition salt. The above sydnonimine compounds are useful for the treatment of troubles of the circulatory system and can be produced by contacting a 3-[4-(benzoylalkyl)-piperazin-1-yl]sydnonimine compound represented by the following for- mule wherein R' and n are as defined, with a carboxylic acid represented by the following formula wherein R 2 is as defined.
