A solution of the product from Example 85 (5 g, 17.5 mmol) in 80 mL acetic acid was treated with sodium cyanoborohydride (2.2 g, 35 mmol) portionwise under an argon atmosphere and stirred for 4 hours. Water (100 mL) was added to the reaction mixture, and the resulting solid was collected by filtration and dried (3.9 g, 78% yield).
