Versuchsvorschrift

1-((Z)-2-Amino-1,2-dicyanovinyl)-3-(trans-4-hydroxycyclohexyl)urea. cis-4-Hydroxycyclohexane carboxylic acid (2.0 g, 13.87 mmol), triethylamine (1.40 g, 13.87 mmol) and diphenylphosphorylazide (3.81 g, 13.87 mmol) were combined in toluene and stirred at room temperature. The reaction was monitored via thin layer chromatography (50% ethyl acetate in hexanes, KMnO4 stain). After 30 min the solution was condensed under reduced pressure and the oil diluted with acetonitrile (30 mL) followed by the addition of diaminomaleonitrile (1.57 g, 14.56 mmol). The solution was heated to 65° C. for 16 h. The solution was condensed under reduced pressure and partitioned between water and ethyl acetate (3×), organics combined, dried over magnesium sulfate, filtered and solvent removed to afford the crude product. The crude oil was purified using Biotage silica gel chromatography (70-100% ethyl acetate in hexanes followed by 10% methanol in ethyl acetate) to afford the title compound (1.90 g, 37%). MS (ESI) m/z 250.1 [M+1]+.
