実験手順
To the product of Step 3 (3 g, 9 mmol) was added a 1.0M TBAF solution in THF (9.3 mL, 9.3 mmol) and the mixture heated to reflux for 1.5 hours, cooled to room temperature and then diluted with 500 mL of ethyl acetate. The solution was successively washed with water (2×100 mL), brine (2×100 mL), dried (MgSO4), filtered, and concentrated in vacuo to provide the title intermediate.
