実験手順

To a solution of diethyl (2-{cyclopropyl[1-({[(2,4-dichlorophenyl)methyl]amino}-carbonyl)-2-oxopropyl]amino}-2-oxoethyl)phosphonate (0.043 g, 0.087 mmol, prepared as described below) in anhydrous tetrahydrofuran (2.5 ml) at 0° C. was added lithium chloride (0.016 g, 0.39 mmol). The mixture was stirred until all of the lithium chloride dissolved and then triethylamine (0.066 ml, 0.87 mmol) was added. The mixture was allowed to warm to room temperature and stirred for 18 hrs. Evaporation of the solvent in vacuo and purification of the resulting residue by mass-directed automated HPLC gave 1-cyclopropyl-N-[(2,4-dichlorophenyl)methyl]-3-methyl-5-oxo-2,5-dihydro-1H-pyrrole-2-carboxamide (0.012 g) as a white solid.
