Reaction Steps

To 13.1 g (31.8 mmol) of 30 was added 128 mL of a 1 M solution of TBAF in THF and the reaction was stirred for 16 h at room temperature. The reaction mixture was then quenched with saturated solution of aq. NH4Cl and THF was evaporated under reduced pressure. The aq. solution was then diluted with 200 mL of water and the product was extracted with Et2O (3×), the combined organic layers were then washed with brine (1×), dried over MgSO4 and the solvent was removed under reduced pressure. The crude was then purified by combiflash using hexane/ethyl acetate as eluent to furnish 7.1 g of target product 31 in 75% yield as colorless oil.
