A process for producing an aryl carbamate of a high purity at a high yield by reacting a diaryl carbonate with an amine compound having one or more hydrogen atoms bonded to the N position in the presence of carboxylic acid(s) of the following general formulae (I): R1-COOH and/or (II): R2-COOH (wherein R1 represents an alkyl or cycloalkyl group having a carbon atom at the α-position, which is bonded to only one hydrogen atom, and R2 represents an alkyl group having a carbon atom at the α-position, which is not bonded to a hydrogen atom).

The invention provides methods of preventing, treating or ameliorating autoimmune diseases, such as diabetes and celiac disease, by decreasing the binding of MHC class II molecules to antigenic peptides or fragments of antigenic peptides of the autoimmune disease by the administration of small organic compounds. The invention also provides pharmaceutical compositions comprising the therapeutically effective small organic compounds and methods of using the same.
