Reaction Steps
To a solution of the product from Example 94A (5.92 g, 39.2 mmol) in 100 mL of THF was added MeOH (1.26 g, 39.2 mmol). The mixture was heated at reflux for 2 hours then allowed to cool to ambient temperature. The solvent was removed under reduced pressure and the crude product was dissolved in 100 mL of EtOAc/hexanes (1:1). The mixture was filtered through a ½″ silica gel frit and the frit was washed with an additional 50 mL of EtOAc/hexanes (1:1). The solvent was removed in vacuo to provide a pale yellow oil which solidified on standing. The product (4.56 g, 80% crude yield) was used without further purification.
