Versuchsvorschrift

To a solution of compound 27d (67 mg, 0.33 mmol) in THF (2 mL) was added oxalyl dichloride (43 μL, 0.50 mmol) dropwise at 0° C., followed by the addition of 2 drops of DMF. The resultant mixture was stirred at 0° C. for 3 h, and then was warmed up to room temperature over 18 h. The solvents were removed under reduced pressure. The resultant residue, crude compound 27e, was dried under reduced pressure for 2 h and used in the following step without further purification.
