N-[1-(2-Benzo[b]thienyl)ethyl]-N'-carbamoylurea and 1-[1-(2-Benzo[b]thienyl)ethyl][1,3,5]triazine-2,4,6-trione Methanol Solvate

The title compounds, C₁₂H₁₃N₃O₂S and C₁₃H₁₁N₃O₃S.CH₄O, were prepared by treating the precursor urea, [1-(2-benzo[b]thienyl)ethyl]urea, with N-chlorocarbonyl isocyanate. The products were isolated by preparative thin-layer chromatography. Analytical samples were obtained by crystallization from methanol and the crystal structures of both compounds were determined.
