Procedure

A procedure similar to that described in Example 2, above, was followed, but using 1.25 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-naphthyloxy)butyryloxy]-2-methyl-1-naphthyl]ethyl}tetrahydro-4-t-butyldimethylsilyloxy-2H-pyran-2-one [prepared as described in Example 100, above] and 24.6 ml of a 1.0 molar solution of tetrabutylammonium fluoride in tetrahydrofuran, to give 0.25 g of the title compound as white crystals, melting at between 124° and 127° C.
