1,1'-Carbonyldiimidazole → HCID 57714139, compound

Participants

Reaction Steps

To a suspension of N-benzyliminodiacetic acid (10 mmol) in THF (30 ml), 1,1′-carbonyldiimidazole (22 mmol) is added with stirring. The reaction mixture is refluxed with stirring for 15 minutes. Propargylamine (10 mmol) is added and then reaction mixture is stirred at 90° C. for 1 day. The organic solvent is evaporated and then the residue is dissolved in AcOEt. The organic layer is washed with 2×100 ml 0.1N HCl and then dried over sodium sulfate. The solvent is concentrated under vacuum. The purification of the residue by silica gel column chromatography affords 1.5 g of title compound in 62% yield. Rf=0.24 (n-hexane:AcOEt=3:1)
