실험 절차

1.48 g (9.1 mmol) of 2,2-diethylbutyryl chloride were added to a solution of 1.0 g (1.8 mmol) of (4R,6R)-6-{2-[(1S,2S,6S,8S,8aR)-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] 1.67 g (11.3 mmol) of 4-(1-pyrrolidinyl)pyridine and 1.0 ml (7.1 mmol) of triethylamine in 10 ml of toluene, and the resulting mixture was heated under reflux for 10 hours. At the end of this time the reaction mixture was worked-up following a procedure similar to that described in Example 5, above, to give 1.09 g (89% yield) of the title compound.
