The mixture was cooled to space temperature, then, the mixture was poured into ice cold water and neutralised with Protein A Magnetic Beads custom synthesis sodium bicarbonate remedy, right after the mixture was washed with water and DCM for two instances, the DCM layer was separated and dried over anhydrous sodium sulphate. Fatherly DCM solvent was removed in vacuo, the residue was purified by column chromatography on silica gel to give the corresponding merchandise 4a.
