In this novel one-pot method, aminocarboxylic acids are reacted with alcohols in the presence of hydrogen chloride to give aminocarboxylate hydrochlorides, which are subsequently phosgenated in the presence of liquid acid chlorides as solvent or suspending agent, if appropriate after having removed the excess alcohol by distillation. |
