Procedure
Methyl 3-(4-{4-[1-(2-chlorophenyl)ethoxycarbonylamino]-3-isoxazolyl}benzylsulfanyl)propionate (110 mg, 0.232 mmol) was subjected to optical resolution by high performance liquid chromatography (HPLC) (hexane:ethanol=8:2) using CHIRALCEL OD column (2 cm I.D.×25 cm L; DAICEL CHEMICAL IND., LTD) to give the title compound (R form, 54 mg, 49%) along with its S form (55 mg, 50%). The optical purity was determined by HPLC analysis using an optically active column.
