Procedure

A procedure similar to that described in Example 2, above, was followed, but using 0.94 g of (4R,6R)-6-([1S,2S,6S,8S,8aR]-2-{1,2,6,7,8,8a-hexahydro-6-t-butyldimethylsilyloxy-8-[(2RS)-2-(3,4-dimethylphenoxy)butyryloxy]-2-methyl-1-naphthyl}ethyl)tetrahydro-4-t-butyldimethylsilyloxy-2H-pyran-2-one [prepared as described in Example 40, above] and 31.0 ml of a 1.0 molar solution of tetrabutylammonium fluoride in tetrahydrofuran, to give 0.26 g of the title compound as white crystals, melting at between 137° and 139° C.
