Procedure
A solution of 0.15 g (0.28 mmol) of 2-(S)-(3,5-Bis(trifluoromethyl)benzyloxy)-4-(methoxycarbonylpentyl)-3-(R)-phenylmorpholine (from Example 64) in 3 mL of MeOH was saponified by treating with 0.5 mL of 5N NaOH for 40 min at 65° C. The solution was cooled, concentrated and the residue was diluted with water. The aqueous solution was adjusted to pH 6 by adding 2N HCl and it was extracted with EtOAc. The organic layer was washed with brine, dried and concentrated. The residue upon chromatography on a flash column with 50% EtOAc/hexane furnished 0.13 g (89%) of the product
