Procedure

To a solution of 63c (0.97 mmol, 300 mg) in CH2Cl2 was added DAST (1.015 mmol, 0.133 mL) dropwise at −78° C. under N2. The reaction was kept at −78° C. for 30 min and then quenched with aqueous NaHCO3 solution at low temperature. Additional CH2Cl2 was added to the reaction and the organic solution was concentrated. The crude material was purified flash column chromatography (silica gel, 10% EtOAc/hexanes) to give 63d.
