Procedure
To 5c (3.7 mmol) in EtOH (60 mL) was added triethyl orthoformate (10 mL), and the reaction was heated to 65° C. overnight. After cooling to room temperature, the mixture was concentrated, and the residue was purified by silica gel chromatography (100% EtOAc) to give the desired product, 5d.
