Procedure
1,1-Dimethylethyl methyl bicyclo[2.2.2]octane-1,4-dicarboxylate (495 mg) was dissolved in methanol (5 mL). To this solution, a 2 mol/L aqueous sodium hydroxide solution (0.92 mL) was added and the mixture was stirred at room temperature for 8 hours and then at 50° C. for 2 hours. Methanol in the mixture was evaporated under reduced pressure. Water was added to the resulting residue and the mixture was washed with diethyl ether and was neutralized with 3 mol/L hydrochloric acid. The resulting crystals were filtered, washed with water, and dried under reduced pressure to give 1,1-dimethylethyl hydrogen bicyclo[2.2.2]octane-1,4-dicarboxylate (344 mg).
