Procedure

A procedure similar to that described in Example 1, above, was followed, but using 597 mg of 2-(4-nitrophenoxy)-2-methylpropionic acid and 731 mg 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 give880 mg of the title compound as a colorless foam.
