Reaction Steps

The product from Example 85 (3.0 g, 4.8 mmol) was diluted with 10 mL each of tetrahydrofuran, water, and methanol; 15 mL of 1 N sodium hydroxide (14.4 mmol) was added; and allowed solution to stir overnight at room temperature. The solution was concentrated, water added, and neutralized with 1 N phosphoric acid. The aqueous layer was extracted with methylene chloride, dried over anhydrous sodium sulfate, and concentrated in vacuo. Purified by Biotage in gradient 10-30% ethyl acetate/hexanes, then flushed column with ethyl acetate to 5% methanol/ethyl acetate. Yielded 2.3 g (78%) of product. MH+=619.6
