反应详情

The crude acetoxy compound from Example 14 is dissolved in 250 mL methanol, and 25.0 g of potassium carbonate is added all at once. After stirring for 2 hours, the reaction mixture is filtered and concentrated. The concentrated residue is partitioned between 200/200 mL water/ethyl acetate. The organic layer is removed, washed with brine, dried and concentrated. The crude material is purified by flash chromatography using silica gel to afford the pure product.
