TL;DR: In this paper, a method for the synthesis of 1,3-dialkyl-4-[(arylmethylidene)amino]glycolurils was developed based on nucleophilic substitution of the sulfur atom with the oxygen atom in the corresponding thioglycoluril via alkylation of the latter followed by acid hydrolysis of alkylsulfanyl derivatives of thioglobalurils, both with the isolation of alknsulfanyl intermediates and by the one-pot method.
