Reaction Steps

2 g pulverized molecular sieve (4 Å) and 1.27 g tetrabutylammoniumfluoride hydrate were added to a solution of 2.0 g (20S)-4,4-dimethyl-20-[((triisopropylsilyl)oxy)methyl]-pregna-5,7-dien-3β-ol in 50 ml tetrahydrofuran were added. The mixture was stirred overnight at room temperature, concentrated under reduced pressure and purified by column chromatography to give 1.17 g of (20S)-4,4,20-trimethyl-pregna-5,7-dien-3β,21-diol benzoate.
