METHOD FOR SYNTHESIZING 5-(CHLOROPHENYL)-2-FURANCARBOTHIOAMIDE COMPOUND FROM FUROIC ACID

Current Patent Assignee: DUKSUNG WOMENS UNIVERSITY - KR101900374, 2018, B1

Patent Family Members: KR101900374 B1

Abstract

In an embodiment of the present invention, provided is a method for preparing a 5-chlorophenyl-2-furancarbothioamide-based compound, the method comprising: a first step of preparing 5-chlorophenyl-2-furoic acid by making benzene diazonium chloride compound, prepared by making aniline chloride and sodium nitrite react to each other, react with 2-furoic acid; a second step of preparing a 2-pyridyl ester compound by treating 5-chlorophenyl-2-furoic acid, prepared in the first step, with di-2-pyridyl carbonate (2-DPC) and preparing 5-(chlorophenyl)-2-furancarboamide by adding amine to the 2-pyridyl ester compound; and a third step of treating 5-chlorophenyl-2-furancarboamide, prepared in the second step, with Lawessonandprime;s reagent.
