Reaction Steps

A solution of (5R)-3-[6-(2-{[tert-butyl(dimethyl)silyl]oxy}ethoxy)hexyl]-5-(2,2-dimethyl-4H-1,3-benzodioxin-6-yl)-1,3-oxazolidin-2-one (0.79 g) in THF (30 ml) was treated with tetrabutylammonium fluoride on silica gel (3.08 g) and the mixture stirred under nitrogen at 20° C. for 2.75 h. The reaction mixture was filtered and the filtrate evaporated in vacuo to give a residue which was purified by SPE on silica. Elution with dichloromethane, then EtOAc followed by solvent evaporation in vacuo gave the title compound (0.56 g). LCMS RT=3.05 min, ES+ve 394 (MH)+.
