실험 절차

4-[1-(4-Cyclohexylphenyl)-3-(4-trifluoromethylsulfanylphenyl)ureidomethyl]benzoic acid (0.32 g, 0.606 mmol) was dissolved in DMF (7 mL) and HOAt (0.10 g, 0.727 mmol) and EDAC (0.14 g, 0.727 mmol) were added. The mixture was stirred for 30 min. Then (R)-3-amino-2-hydroxypropionic acid methyl ester hydrochloride (0.14 g) and diisopropylethylamine (0.16 mL, 0.909 mmol) were added. The reaction was stirred overnight. The reaction mixture was transferred to a separatory funnel with ethyl acetate (30 mL) and water (15 mL) and extracted. The aqueous phase was extracted once more with ethyl acetate (15 mL) and the combined organic phases were washed with hydrochloric acid (0.2 N, 3×10 mL) and an aqueous solution of saturated sodium chloride (3×10 mL), dried over magnesium sulphate, filtered and concentrated in vacuo. The residue was purified on a column (silica gel, 30 g) using a mixture of ethyl acetate and n-heptane (200 mL, 40:60 and 450 mL 1:1) as eluent to afford 0.33 g of (R)-3-{4-[1-(4-cyclohexylphenyl)-3-(4-trifluoromethylsulfanylphenyl)ureidomethyl]benzoylamino}-2-hydroxypropionic acid methyl ester.
