ABSTRACT:
In the synthesis of an amide compound through reaction of an acyl fluoride group-bearing compound with an amino compound, a reaction mixture contains the amide compound and hydrogen fluoride or a hydrofluoric acid amine salt. The amide compound is recovered in high purity form by adding an oxide, carbonate or hydroxide of an alkaline earth metal to the reaction mixture to convert the hydrogen fluoride or hydrofluoric acid amine salt to an alkaline earth metal fluoride salt that can be readily removed by filtration.
