Procedure

A mixture of the product of Example 75 step i) (300 mg), (R)-2-(hydroxymethyl)piperazine-1-carboxylic acid, tert-butyl ester (465 mg) and sodium triacetoxyborohydride (608 mg) in dichloromethane (20 mL) was stirred under nitrogen for 16 hours. The reaction was partitioned between dichloromethane and water, the organics were then collected and concentrated to dryness. The residue was purified by HPLC to give the title compound (230 mg) as a solid.
