Procedure

To a solution of methyl Z-4-[[2-butyl-5-[(2,5-dioxo-4-imidazolidinylidene)methyl]-1H-imidazol-1-yl]methyl]benzoate (0.200 g, 0.524 mmol) in DMF (2 mL) is added sodium hydride (80% in oil, 0.02 g, 0.67 mmol) and the mixture stirred for 5 minutes. (Trimethylsilyl)ethoxymethyl chloride SEM-C1 (0.100 mL, 0.536 mmol) is added and the mixture allowed to stir for 16 hours. The solvents are removed in vacuo and the residue dissolved in ethyl acetate and water. After drying the organic fraction over MgSO4, the required product is isolated by chromatography, eluting with 0.5% methanol in chloroform. Crystallized from ether.
