Procedure

To a solution of EXAMPLE 357A (0.59 g) in tetrahydrofuran (5 mL) was added lithium aluminum hydride (1.80 mL) at 0° C. The reaction was removed from the ice bath and allowed to warm to room temperature. The reaction was quenched by the dropwise addition of 0.6 ml of water followed by 0.2 ml of 2N aqueous NaOH. The reaction was filtered through elite and rinsed with ethyl acetate (50 mL). The mixture and the residue was loaded onto silica gel (Reveleris 40 g) and eluted using a gradient of 0.75% to 7.5% methanol/dichloromethane over 30 minutes (flow=40 mL/minutes) to provide the title compound.
