Reaction Steps

The title product of Example 1 (25.0 g, 58.6 mmol) dissolved in 150 ml of tetrahydrofuran (THF) was combined with a solution of potassium hydroxide (KOH, 7.7 g, 0.12 mmol) dissolved in 375 ml of water. After this reaction was stirred for 4 h, it was poured into a mixture of 2.5N KHSO4 (400 ml) and CH2Cl2 (500 ml). The organic layer was separated and the aqueous (pH2) was extracted 3×100 ml of CH2Cl2. The combined organics were washed with 150 ml of brine, dried over Na2SO4, and stripped of all solvent under reduced pressure. The residue, after in vacuo drying, yielded 25 g of the title product as a white powder. This material was used without further purification.
