Pravastatin Diol Lactone Di-(tert-butyldimethylsilyl) Ether → (4R,6R)-6-([1S,2S,6S,8S,8aR]-2-(1,2,6,7,8,8a-Hexahydro-6-t-butyldimethylsilyloxy-8-[(2RS)-2-(4-bromophenoxy)butyryloxy]-2-methyl-1-naphthyl}ethyl)tetrahydro-4-t-butyldimethylsilyloxy-2H-pyran-2-one

Participants

Reaction Steps

A procedure similar to that described in Example 1, above, was followed, but using 0.94 g of (2RS)-2-(4-bromophenoxy)butyric acid and 1.0 g of (4R,6R)-6-{(1S,2S,6S,8S,8aR)-2-[1,2,6,7,8,8a-hexahydro-6-t-butyldimethylsilyloxy-8-hydroxy-2-methyl-1-naphthyl]ethyl}tetrahydro-4-t-butyldimethylsilyloxy-2H-pyran-2-one [prepared as described in Example B, above], to give 1.38 g of the title compound as a colorless foam.
