Reaction Steps

To a solution of tert-butyl-4-(benzyloxy)-3-hydroxybutanoate XXXV [Tetrahedron (1993), 49(10), 1997-2010] (2.3 g, 8.84 mmol) in DCM (100 mL) at 0° C. was added 2,6-lutidine (3.07 mL, 26.52 mmol) and TBSOTf (4 mL, 4. 17.68 mmol). After stirring for 16 h at 0° C., the reaction was diluted with EtOAc (400 mL). The mixture was washed with 1N HCl, saturated aq NaHCO3, water and dried. The extract was dried (MgSO4) and concentrated under reduced pressure. Purification of the crude product by column chromatography (100% hexane→25% EtOAc/hexane) afforded tert-butyl 4-(benzyloxy)-3-(tert-butyldimethylsilyloxy)butanoate XXXVI (3.1 g, 8.15 mmol, 92.1% yield) as a colorless oil.
