  • Synthesis of salicylamides with improved reaction kinetics and improved effective yields
    Patent number: 4701527
    Abstract: A method of synthesizing with improved reaction kinetics and improved effective yields salicylamide compounds of the formula: ##STR1## wherein R.sub.1 is a substituent selected from the group consisting of --H, --COC.sub.n H.sub.2n+1 and --C.sub.n H.sub.2n+1 wherein n is an integer with a value of from 1 through to about 15, R.sub.2 is a substituent selected from the group consisting of --H, --CN, --NO.sub.2, --F, --Cl, --Br, --I, --CF.sub.3, --CBr.sub.3, --CCl.sub.3, --CI.sub.3 and R.sub.1 and R.sub.3 is an R.sub.2 substituted heterocyclic compound selected (e.g.) from the group consisting of furan, thiazole, benzothiazole and purine which comprises reacting a phenyl salicylate ester bearing an R.sub.1 substituent on the benzene ring of the salicylic acid portion thereof with an R.sub.2 substituted aniline or a heterocyclic amine NH.sub.2 --R.sub.
