N,N-Disubstituted thioureas (1a-g) can be cyclized by use of oxalyl dichloride to the 4,5-dioxo-2-thioxo-perhydro-imidazolyl-pyrimidine-2(H)-thiones (2a-g) in good yields (50-68%). The structures of these compounds were determined by elemental analysis, IR, (1)H NMR and (13)C NMR spectroscopic measurements.
