PROCEDURE

实验过程

2.0 g of 21-acetoxy-6α-methyl-17-propionyloxy-11β-trifluoroacetoxy-4-pregnene-3,20-dione is agitated in 50 ml of methanol and 2.5 ml of triethylamine for 4 hours at room temperature. The crude product is purified on 300 g of silica gel with a methylene chloride-acetone gradient (0-15% acetone), thus isolating 1.2 g of 21-acetoxy-11β-hydroxy-6α-methyl-17-propionyloxy-4-pregnene-3,20-dione.
