Researches ok heterocyclic rings containing nitrogen and sulfur II. Orotylamino acids, their esters, and salts of orotic acid with amines

Esters of orotylamino acid are synthesized by reacting orotyl chloride with glycine and- and-alanine esters. Orotylamino acids are prepared by reducing the benzyl ester of orotylglycine, or by reacting orotyl chloride with sodium salts of amino acids. A series of salts of orotic acid are prepared by reacting orotic acid with amines.For Part I see 8].
