実験手順

A solution of methyl ({[2-((1R)-1-{2-[(benzyloxy)amino]-2-oxoethyl}-4-cyclohexylbutyl)-5-methyl-1,3-oxazol-4-yl]carbonyl}amino)acetate (Preparation 99) (158 mg, 0.32 mmol) in 1,4-dioxan (5 ml) was treated with sodium hydroxide solution (1M) (470 □1,0.47 mmol). The mixture was stirred for 1 hour under a nitrogen atmosphere. The reaction mixture was diluted in water and washed with ethyl acetate. The aqueous layer was acidified with solid citric acid and extracted with ethyl acetate. The organic layers were dried over anhydrous magnesium sulphate, filtered and the solvent removed under reduced pressure to afford the title compound (61 mg).
