An efficient, one-pot procedure for the Hofmann rearrangement of aromatic and aliphatic amides provides methyl and benzyl carbamates in high yields in the presence of N-bromoacetamide and lithium hydroxide or lithium methoxide. β-Phenylamino amides gave five-membered cyclic ureas stereospecifically.
