A suspension of 2-amino-4-oxo-4,5-dihydro-imidazole-1-carboxylic acid benzyl ester (93.2 mg, 0.40 mmol), 2-chloro-4-fluoro-benzylbromide (89.2 mg, 0.40 mmol) and K2CO3 (83.01 mg, 0.60 mmol) in acetonitrile (10 mL) was heated to reflux under argon for 1 hr. Cooled to r.t. and the reaction mixture was partitioned between EtOAc and water. The organic layer was dried over Na2SO4 and concentrated to give a residue which was triturated with EtOAc and filtered to give 2-(2-chloro-4-fluoro-benzylamino)-4-oxo-4,5-dihydro-imidazole-1-carboxylic acid benzyl ester as a white solid (73.0 mg, 48.7%).
