実験手順

To a solution of compound 52d (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 52e (light pink powder), which was used in the next reaction without further purification.
