PROCEDURE
实验过程
A mixture of 1.76 g of 17α-acetoxy-6β-chloro-7α-hydroxy-2-oxa-4-pregnene-3,20-dione, 1.11 ml of methanesulfonyl chloride and 5.2 ml of pyridine was stirred for 1 hour under ice cooling, and then for 12 hours at room temperature. Ice-cooled water was added to the reaction mixture, and the precipitated crystals were collected by filtration to give 2.01 g of 17α-acetoxy-6β-chloro-7α-mesyloxy-2-oxa-4-pregnene-3,20-dione.
