실험 절차

A solution of tert-butyl (3R)-6-cyclohexyl-3-(3-{[methyl(methylsulfonyl)amino]methyl}-1,2,4-oxadiazol-5-yl)hexanoate (preparation 6) (264 mg, 0.60 mmol) in 4M HCl in dioxan (2 ml) was stirred at room temperature for 20 hours. Further 4M HCl in dioxan (2 ml) was added and stirred for a further 3 hours. A few drops of concentrated HCl was added and the reaction mixture was stirred at room temperature for 18 hours. The solvent was removed under reduced pressure to afford the title compound (245 mg—contained some dioxan as impurity).
