Procedure
2-Ethoxycarbonyl-3-(3-fluoro-phenyl)-pentanedioic acid diethyl ester (2-2) (6.90 g, 19.5 mmol) was treated with 6 N HCl (150 mL). The mixture was refluxed for 24 hr, poured into 200 mL ice-water and extracted with EtOAc (×3). The combined organic layers were washed with brine, dried (Na2SO4) and concentrated to provide 2-3 as a solid which was used in the next step without further purification.
