실험 절차

Compound 41 (4.37 g, 0.0164 mol) was dissolved in THE Molecular sieve (10 g of 3A) was added followed by TBAF (32.75 mL, 0.0328). The reaction mixture was stirred for 5 h at rt. Diluted with ethyl acetate and washed several times with water, brine and the organic layer was dried and concentrated in vacuo to an oil that was subjected to flash chromatography (30% EtOAc-70% hexanes) to give 02.3 g (90%) of the desired material 42. 1H NMR DMSO d6 11.8 (bs, 1H), 8.2 (s, 1H), 8.1 (s, 1H), 7.5 (s, 1H), 6.5 (s, 1H).
