Treatment of primary and secondary amines with tert- butylmesitylenesulfonoxycarbamate and a base afforded tert-butoxyurea, which when treated with an acid ultimately yielded substituted N-hydroxyureas. It is proposed that this proceeded via the generation of t-butoxy isocyanate in situ. This method allows for the synthesis of both mono and disubstituted N-hydroxyureas.

Chloromethyl carbamates were prepared by the reaction of chloromethyl chloroformates with amines and found to produce mono-, symmetrically or unsymmetrically di- and trisubstituted ureas including their N-hydroxy and N-alkoxy derivatives in moderate to good yield.
