To a suspension of 9.0 g silica gel and PCC (7.7 g, 35.7 mmol) in 300 mL DCM was added 4-(tert-Butyl-diphenyl-silanyloxy)-butan-1-ol (6.0 g, 18.3 mmol) in 50 mL DCM. The mixture was stirred for 3 h at room temperature and then the resulting suspension filtered thorough a pad of celite/florisil and rinsed with DCM. The solvent was evaporated and the product was isolated by flash column chromatography eluting with 0% to 30% ethyl acetate/hexane to give the title compound (4.7 g) as a light yellow oil.
