Reaction Steps
After stirring a mixture of 4-bromo-2,5-difluorobenzoic acid and thionyl chloride for one hour at 80° C., the solution was removed and an oily substance was obtained. A mixture of the obtained oily substance, 3-aminothiophene-2-carboxamide, N,N-diisopropylethylamine and THF was stirred for two hours under ice cooling to give 3-[(4-bromo-2,5-difluorobenzoyl)amino]thiophene-2-carboxamide.
