실험 절차
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). The mixture was heated to reflux for 1.5 hours, cooled to room temperature, and diluted with 500 mL of ethyl acetate. The solution was successively washed with water (2×100 mL) and brine (2×100 mL), dried (MgSO4), filtered, and concentrated in vacuo to provide the desired product.
