Reaction Steps

Diethyl 2-(4-chloro-2,5-difluorophenyl)malonate (330 mg, 1.08 mmol) was dissolved in EtOH (1 mL), and then NaOH (0.6 mL, 5N) was added. The resulting solution was stirred at ambient for 12 hours. At this time, the reaction mixture was heated to 60° C. for 3 hours, after which it was acidified to a pH of 1 with HCl (1N). The reaction was diluted with water (1 mL) and then extracted twice with diethyl ether. The combined organics were dried over magnesium sulfate, filtered and concentrated to give 2-(4-chloro-2,5-difluorophenyl)acetic acid which was used without further purification.
