Procedure

The amino acid 8 prepared in Example 9 was added to a refluxing solution of lithium aluminum hydride (62 mg, 1.63 mmol) in TI-IF (10 ml). The reaction mixture was heated at reflux for 12 hours, subsequently cooled to 0° C. and 10 M NaOH was added and stirred for 20 minutes. Ethyl acetate (20 ml) was added and the mixture was filtered through Celite and magnesium sulfate. The filtrate was concentrated under vacuum and purified by column chromatography (Silica gel, 50% MeOH in CH2Cl2) to provide 41 mg of the product, VPC104059 (21%, two steps).
