Reaction of dibepin with amino acids on chromatographic paper

A method was developed for the development of amino acids and some of their derivatives on Chromatographic paper by means of dibepin-8-2,3(CO),6,5(CO)-dibenzoylene-4-pyridyl]-l-naphthoyl chloride. The sensitivity was 2 g in the case of glycine ethyl ester hydrochloride.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 3, pp. 357–358, March, 1972.
