A synthetic method for 2-amino-1-(1-indol-3-yl)ethylphosphonic acid and 2-amino-1-(1-methylindol-3-yl)ethylphosphonic acid hydrochlorides, i.e., new indole-containing functionalized aminophosphonic acids, is proposed. The reactions are carried out at room temperature in LiOH solution followed by precipitation of the salts using HCl. The synthesized indolylaminoethylphosphonic acids, the molecules of which contain an indole ring and amine and phosphonic groups, could be considered synthetic precursors of functionalized tryptamine analogs.
