A mixture of starting material (1 equiv.), quinuclidine (0.3 equiv.), Me4NBF4 (1 equiv.) and HFIP (10 equiv.) in CH3CN (5 mL) was placed in an ElectraSyn vial, equipped with two IKA graphite electrodes, and electrolyzed in a Electrasyn 2.0 at room temperature, under constant current (5 mA, j = 2.00 mA/cm 2 ). The reaction progress was monitored by TLC (10% MeOH in DCM). Acetonitrile and HFIP were subsequently co-evaporated with water under reduced pressure, upon which celite and MeOH were added and the slurry was concentrated to dryness at 40 o C. The resulting mixture was pulverized, loaded on top of a silica gel column and subsequently eluted (5 to 10% MeOH in DCM). Fractions containing the desired product were collected and the solvent was removed in vacuo.
