Abstract
o-Methoxycarbonyl-phenyl isocyanate reacts with mono-aminoalkyl orthophosphoric and sulfuric acids to yield the corresponding 1,2,3,4-tetrahydroquinazoline-2,4-dione-3-ethyl phosphoric (or sulfuric) monoesters which are isolated as sodium salts. 1,2,3,4-Tetrahydroquinazoline-2,4-dione-3-ethyl phosphoric acid has been isolated by adding hydrochloric acid to an aquous solution of its sodium salt.
