The invention relates to compounds represented by the general formula (I): and pharmaceutically acceptable salts thereof, wherein n is an integer from 1 to 5; p is an integer from 0 to 4; R1 is selected from the group consisting of a hydroxyl group, an alkoxy group, a thiol group, and a thioether group; R2 and R3 are independently a methylene group or a nucleophile, with the proviso that at least one of R2 and R3 is a nucleophile group; Z is an oxygen (O) atom or sulfur (S) atom; T is hydrogen or an optionally substituted aliphatic group; with the proviso that when n = 2, R1 is not -OCH3 on the carbon-3 position of the phenyl group and R1 is not -OH on the carbon-4 position of the phenyl group.

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.
