Procedure

A solution of Example 252A (1.0 g, 3.1 mmol) in THF (5 mL) at 0° C. was treated dropwise with 1M LiAlH4 in THF (3 mL), warmed to room temperature, stirred for 2 hours, quenched with methanol (1 mL), treated with 1N NaOH (50 mL), and extracted with ethyl acetate (3×100 mL). The combined extracts were washed with water and brine, dried (Na2SO4), filtered, and concentrated to provide the desired product. MS (APCI) m/e 323(M+H)+.
