Procedure

Cis-2-(4-pyridylcarbonyl)cyclohexanecarboxylic acid was dissolved in 10% sodium hydroxide (300 mL) and stirred at 20° C. for 16 h. The aqueous solution was extracted with diethyl ether (200 mL) and then acidified to pH=4 by addition of 6 M hydrochloric acid. The resulting precipitate was collected and recrystallized from hot water, to give (1S, 2R)-2-(4-pyridylcarbonyl)cyclohexanecarboxylic acid, as a white solid (4.8 g, 40% from cis-1,2-cyclohexanedicarboxylic anhydride).
