Procedure
A 500 mL flask was charged with 1-(cyclopentadienyl)-3,3,5,5-tetramethylcyclohexane (11.87 g, 58.1 mmol), 100 mL methanol, acetone (30 mL, 430 mmol), and pyrrolidine (1.0 mL, 12 mmol). After stirring for 52 hours, 5 mL of acetic acid were added, along with 200 mL water and 100 mL diethyl ether. The organic layer was isolated and the aqueous layer was extracted with diethyl ether (3×50 mL). The combined organic layers were extracted with H2O (3×30 mL) and 10% aqueous NaOH (3×30 mL). The organic layer was dried over MgSO4, filtered, rotavapped, dried in vacuo, and pushed through a short column of alumina to provide the product in quantitative yield as a yellow oil. MS (GC-MS) m/z 244.4 (M+).
