Concept introduction:
The method used to synthesise amides from amines and acid chlorides in the presence of a base is known as Schotten Baumann. It is typically used to indicate two-phase solvent system in which one is water and other is an organic solvent. It is a condensation reaction in which two molecules combine to form a larger molecule.
