Finally, I need to purify the final product, which involves removal of AlCl3 from the solution. How is this achieved? Is there a method to first remove the AlCl3 before evaporation into dry powder?
Under anhydrous conditions, what would be the proper solvent? Either DMSO or diethyl ether? I think DMSO would be safer to use, but evaporation/purification of the final product may be a challenge, since DMSO has a high boiling point (170C). How do you evaporate DMSO?
