Med. Chem. 1995, 38, 3094; 142 mg, 0.8 mmol) in THF (5 ml) was added dropwise to a stirred suspension of lithium aluminum hydride (92 mg, 2.4 mmol) in THF (2 mL) at −10° C. The mixture was stirred at room temperature for 30 min, cooled to 0° C. and treated slowly with water (1 mL). The mix was brought to pH 1 with 2N HCl and extracted with ethyl acetate (3×). The combined extracts were washed with water, brine, dried (MgSO4) and concentrated to give the final product.
