실험 절차
tert-butyl (3R)-6-cyclohexyl-3-[3-(1H-imidazol-2-ylmethyl)-1,2,4-oxadiazol-5-yl]hexanoate (Preparation 102) (530 mg, 1.32 mmol) was treated with trifluoroacetic acid (10 ml) and stirred at room temperature for 1.5 hours. The solvent was removed under reduced pressure and the residue azeotroped from toluene (3×30 ml) and dichloromethane (2×30 ml) to afford the title compound (609 mg).
