A method for the one-step C-ureidoalkylation of phenol, anisole, or aniline rings furnishing ArCH2NHCONHR (Ar = benzyl) products in moderate to good yields is described. With phenol ring systems, higher yields were attained when the reaction was worked up with an acidic ethanethiol addition to cleave any O-ureidoalkylation products that formed during the reaction.
