実験手順

A solution of tert-butyl (3R)-6-cyclohexyl-3-(3-{[3-(4-morpholinyl)-1-azetidinyl]carbonyl)-1,2,4-oxadiazol-5-yl)hexanoate (Preparation 27) (1.32 g, 2.70 mmol) in dichloromethane (15 ml) was cooled to 0° C. and treated with trifluoroacetic acid (5 ml). The resulting mixture was stirred for 3 hours being allowed to warm to room temperature over this time. The solvent was removed under reduced pressure and the residue azeotroped from toluene (×3) then dichloromethane to afford the title compound as a white foam (1.31 g).
