Thiols and amines were benzamidomethylated in water solution at room temper
ature with (benzamidomethyl)triethylammonium chloride (1) in the presence o
f a small quantity of triethylamine (pH>9). Benzamidomethyl thioethers (3a-
d) and (benzamidomethyl)amines or di(benzamidomethyl)amines (5) were obtain
ed in high yields (>90%) as well as S(CH(2)NHBz)(2) in a reaction of 1 with
Na2S. Benzamidomethyl esters RCOOCH(2)NHBz were obtained (60-75%) in react
ions of carboxylic acids with 1 in chloroform or dioxane.
