Procedure

The product of Example 457 (64 mg, 0.12 mmol) was dissolved in anhydrous methanol (2.5 mL) and the resulting solution cooled to 0° C. Sodium borohydride (37 mg, 1 mmol,) was added portionwise over 5 h. The reaction was quenched with water and concentrated. The crude product residue was purified by reverse phase HPLC (water, acetonitrile, formic acid gradient) to afford the titled compound (note elimination of tertiary benzylic alcohol). MS m/z: 515 (m+1).
