The product from Example 66A (1.24 g, 6.6 mmol) in THF (25 mL) was treated with LiAlH4 (2.5 g, 65.9 mmol) at 0° C. The mixture was allowed to warm to room temperature and then refluxed for 1 hour. The mixture was allowed to cool to room temperature and then treated with 1N NaOH carefully followed by water. The mixture was concentrated under reduced pressure and the resulting aqueous mixture was extracted with diethyl ether. The organic extracts were combined, washed with saturated NaHCO3 solution, dried over Na2SO4, filtered, and the filtrate concentrated under reduced pressure to provide the title compound as a yellow oil (286 mg, 23%).
