実験手順

A mixture of diethyl 2-(4-fluorophenyl)malonate (2.98 g, 8.204 mmol, Intermediate 59, step a) and an aqueous 3 M NaOH solution (5 mL) were stirred in a 50° C. oil bath for 48 hours, cooled to RT, poured into ice water and acidified with 6N HCl. The aqueous mixture was extracted with EtOAc. The EtOAc extract was dried over Na2SO4, filtered, and evaporated in vacuo to provide the title compound.
