Procedure

To a solution of EXAMPLE 372A (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 diatomaceous earth and rinsed with ethyl acetate (50 mL). The organics were concentrated and loaded onto silica gel (Reveleris 40 g) and eluted using a gradient of 0.75% to 7.5% methanol/dichloromethane over 30 minute (flow=40 mL/minutes) to give the title compound.
