Procedure

A solution of tert-butyl (3R)-6-cyclohexyl-3-[3-(4-morpholinylcarbonyl)-1,2,4-oxadiazol-5-yl]hexanoate (Preparation 21) (269 mg, 0.62 mmol) in dichloromethane (4 ml) was treated with trifluoroacetic acid (1 ml) and the resulting mixture was stirred at room temperature under a nitrogen atmosphere for 17 hours. The solvent was removed under reduced pressure and the residue azeotroped from toluene to afford the title compound (219 mg).
