Procedure

18.3 g (0.0776 mol) diethylphenylmalonate and 20.5 g (0.0776 mol) 2-aminoimidazole sulfate were dissolved in 93 mL DMF and 35 mL DBU and the mixture was heated to 100° C. for 15 h. The solvent was removed, the residue dissolved in water and re-precipitated by adjusting the pH to 1 with 2 mol/l HCl. The precipitate was collected by filtration to obtain the desired product.
