Purifying the metabolites involves removing TBAPF6 from the crude reaction mixture through methanol recrystallization, as outlined in Procedure B (supporting information), yielding approximately 72% recovery of the crystal. The crystal was identified as TBAPF6 using Similarly, using the optimised conditions CPZ was electro metabolized to CPZ-SO (68%) and the sulfone was detected (CPZ-SO2) but not isolated (Scheme 4).
