実験手順
(Intermediate 136, 0.6 g, 2.3 mmol) in anhydrous tetrahydrofuran (3 mL) was treated with a 1M solution of tetra-n-butyl ammonium fluoride in tetrahydrofuran (4.6 mL, 4.6 mmol) and the resulting reaction mixture was stirred in an ice bath for 5 min. Water was added and the reaction mixture was extracted with ethyl acetate. The organic phase was washed with water and brine, dried over anhydrous sodium sulfate, filtered and evaporated to an oil that was purified by flash column chromatography using 5%-30% ethyl acetate in hexane as the eluent to afford the title compound as a solid (0.33 g, 76%).
