실험 절차

2-(2-(4-(4-Hydroxyphenoxy)phenyl)acetylamino)benzoic acid methyl ester obtained by the Reference Example 24 (315 mg, 0.83 mmol) was dissolved in 20 ml of methylene chloride-THF mixture (1:1 v/v), added with 3-(tert-butoxycarbonylamino)benzyl alcohol (465 mg, 2.1 mmol), 1,1′-azobis(N,N′-dimethylformamide) (359 mg, 2.08 mmol) and tri-n-butyl phosphine (520 ml, 2.1 mmol) and the reaction mixture was stirred over a night. After completing the reaction, the solvent was removed under reduced pressure and the obtained crude residue was purified by silica gel chromatography (elution solvent; hexane:ethyl acetate 75:25 v/v) to obtain the subject compound (404 mg, 0.693 mmol) in the form of a colorless gummy substance. The result of 1H-NMR was consistent with the above structure.
