Procedure

A procedure similar to that described in Example 2, above, was followed, but using 1.31 g of (4R,6R)-6-([1S,2S,6S,8S,8aR]-2-{1,2,6,7,8,8a-hexahydro-6-t-butyldimethylsilyloxy-8-[(2RS)-2-(2-isopropylphenoxy)propionyloxy]-2-methyl-1-naphthyl}ethyl)tetrahydro-4-t-butyldimethylsilyloxy-2H-pyran-2-one [prepared as described in Example 130, above] and 35.4 ml of a 1.0 molar solution of tetrabutylammonium fluoride in tetrahydrofuran, to give 488 mg of the title compound as white crystals, melting at between 138° and 141° C.
