Abstract

NEW MATERIAL:A compound of formula I (R is H, lower alkyl or phenyl which may have a substituent; n is an integer 1W4) and an acid addition salt thereof.
EXAMPLE: 5-Piperazinyl-2-isobutylvalerophenone sulfate.
USE: An ameliorant of peripheral circulation, coronary arterial vasodilator and a remedy for cerebral thrombosis.
