실험 절차

To a solution of diisopropyl (2S,3R)-2-hydroxy-3-{3-[4-(trifluoromethoxy)phenyl]propyl}butanedioate (6.98 g; 16.6 mmol; 1.0 eq.) in THF/water (3/1; 140 mL) was added potassium hydroxide (5.59 g; 99.6 mmol; 6.0 eq.). The reaction mixture was then stirred for 14 h at RT. The aq. layers were acidified with an aqueous solution of HCl to pH 2, extracted with EtOAc. The combined organic layers were then dried over MgSO4 and evaporated to give the title compound as an oil (6.19 g), used in the next steps without further purification.
