PROCEDURE
实验过程
1.5 g (3.0 mmol) of the product 1c were dissolved in 30 ml of pyridine. At 0° C., 1.7 g (10.6 mmol) of phenyl chloroformate were rapidly added dropwise. This reaction solution was stirred for 60 minutes before being stirred into ice-water. The resulting precipitate was isolated, dissolved in methylene chloride, dried and concentrated in vacuo. The resulting residue was crystallized with Et2O/n-pentane. 1.2 g of the intermediate were obtained.
