反应详情

A suspension of N-sulfamyl-3-(methylsulfinyl)propionamidine (5.0 g, 23.5 mmol) in ethanol (100 ml) containing triethylamine (3.6 ml) was refluxed for 20-40 hours. Upon cooling, suspended solids were removed by filtration and the solvent evaporated to give a residue (3.4 g) which was chromatographed on silica gel and eluted with 3-7% methanol/chloroform. Upon concentration of appropriate fractions, the title compound crystallized to give 1.3 g, mp 72°-75°.
