Procedure

A mixture of 20f (118 mg, 0.33 mmol) and benzoylisothiocyanate (63 μL, 0.47 mmol) in DCM (3 mL) was stirred at rt for 3 h. The reaction was concentrated and the residue was purified by flash chromatography (silica gel, 0-10% MeOH/DCM) to give 20 g, as yellow solid (156 mg). LC-MS m/z 513.06 [M+H]+.
