Reaction Steps

A solution of Compound 1b (0.57 g, 1.81 mmol), tetra-n-butylammonium fluoride hydrate (0.57 g, 2.03 mmol) in 38 mL of THF was stirred at r.t. for 2 h. The reaction mixture was poured into water and extracted with EtOAc. The combined organic layers were washed with brine, dried on Na2SO4 and evaporated to dryness in vacuo to afford a residue, which was purified by flash chromatography (EtOAc—Petroleum Ether 1:9) giving the title product (0.21 g).
