A facile method to synthesize N-substituted 2-benzimidazolinones from secondary aromatic amines is presented. Sequential treatment of a secondary aromatic amine with phosgene and methoxylamine afforded an acyclic 3-substituted 3-aryl-1-methoxy urea. Brief

With t-butyl hypochlorite the 1-methoxy-3-arylureas are easily converted into the unstable corresponding 1-chloro-1-methoxy-3-arylureas.Cyclization of the latter under basic conditions gives the 1-methoxy-2-benzimidazolinones.The two steps can be carried
