The reaction mixture was heated at 120° C. for 20 minutes in a microwave reactor. The reaction mixture was cooled and then the solvent removed under vacuum. The residue was purified by MDAP. Fractions containing the desired product were combined and the solvent removed to yield a colourless gum. The product was partitioned between DCM (6 mL) and saturated aqueous NaHCO3 (3 mL) and the organic layer collected via a hydrophobic frit. The solvent was removed under a stream of argon to yield the title compound as a white solid (0.246 g)
