Reaction Steps

20 mg of 3-(2,4-Dichlorophenoxy)dihydrofuran-2-one and 30 mg of ethyl 3-(3-aminophenyl)-2-isopropoxypropanoate were dissolved in 1 ml of toluene, and the solution was heated under reflux for 8 hours. After removing the solvent under a stream of nitrogen, the residue was dissolved in 0.6 ml of ethanol, and 0.12 ml of 5N sodium hydroxide was added thereto, and the mixture was stirred at room temperature for 1 hour. The reaction solution was diluted with 2 ml of water and 0.14 ml of 5N hydrochloric acid, and extracted with ethyl acetate. The organic layer was collected, and the solvent was removed under a stream of nitrogen. The residue was purified by HPLC using a reverse-phase column and a water-acetonitrile-trifluoroacetic acid elution solvent, to give 6.8 mg of the title compound.
