実験手順

A solution of 1-(4-fluoro-phenyl)-4-methyl-2-oxo-imidazolidine-4-carboxylic acid (120 mg, 0.50 mmol) in DCM (15 mL) was treated oxalyl chloride (0.09 mL, 1.03 mmol) and one drop of dry DMF. After stirring 1 hour at room temperature, the solvent was removed in vacuo. To this residue, a solution of 4-amino-2-(trifluoromethyl)benzonitrile (277 mg, 1.49 mmol) and triethylamine (0.28 mL, 2.01 mmol) in dry DCM (10 mL) was added. After stirring overnight at room temperature, the mixture was concentrated in vacuo and the residue purified by flash chromatography to afford the title compound as a tan solid (110 mg, 54%).
