Versuchsvorschrift

To a solution of compound 13d (136.2 mg, 0.5 mmol) in CH2Cl2 (5 mL) at room temperature was added (COCl)2 (0.064 mL, 0.75 mmol), followed by DMF (0.01 mL, 0.125 mmol). The reaction mixture was stirred at room temperature for 18 h. The reaction mixture was then concentrated to give compound 13e as a light pink powder, which was used in the next reaction without further purification.
