Abstract
NEW MATERIAL:An N-substituted trialkoxybenzylpiperazine derivative of formulaI[R is methyl or ethyl; Z is a group of formula II (A is H, lower alkyl, oxymethyl, etc.)].
EXAMPLE: C16H26N2O4.2HCl
USE: Useful as a remedy for ischemic heart deseases, etc. having actions on circulatory systems, e.g. coronary arterial vasodilator or cardioinetic inhibitory actions.
PROCESS: A compound of formula III is reacted with a compound of formula IV by the reductive N-alkylation reaction, e.g. the Leukart-Wallach reaction or catalytic reduction, to give the compound of formulaI.
