Procedure
A procedure similar to that described in Example 1, above, was followed, but using 800 mg of (2RS)-2-(2,4,6-trimethylphenoxy)butyric acid and 1.0 gof (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 1.44 g of the title compound as a colorless foam.
