Abstract

Compounds of the formulae:- <FORM:0937181/IV(a)/1> <FORM:0937181/IV(a)/2> <FORM:0937181/IV(a)/3> <FORM:0937181/IV(a)/4> are prepared by heating 5-methyloxazoline-2-thiol with formalin, diluting with ethanol and then adding, with cooling, an ethanolic solution of morpholine, piperidine, isopropylamine and methylamine respectively. Similarly the compound:- <FORM:0937181/IV(a)/5> is prepared using thiazoline-2-thiol instead of the 5-methyloxazoline-2-thiol with methylamine as the amine.
