New synthesis of sulphonylureas

Roger James Tull; Robert C. O'Neill; Edmund P. McCarthy; James J. Pappas; John M. Chemerda

1-Alkyl-3-arylsulphonylureas have been synthesised by the reaction of sym-1,3-dialkylureas with aryl sulphonamides. The mixed sulphonylureas are formed in good yield by virtue of the symmetry possessed by the dialkylurea component.
