実験手順

3-[(2-Acetylthiomethyl-3-phenylpropionyl)amino]-benzoic acid (compound of Example 68-(b)-[1]) (0.72 g) and potassium iodide (0.37 g) are dissolved in DMF, and thereto are added triethylamine (0.2 g) and 2-chloro-N,N-diethylacetamide (0.33 g) with stirring at room temperature, and the mixture is reacted three nights. The reaction mixture is mixed with water and extracted with ethyl acetate. The extract is washed with water, dried over anhydrous magnesium sulfate, and ethyl acetate is distilled off under reduced pressure. The residue is purified by a medium pressure column chromatography using silica gel (eluant, chloroform). The fractions containing the desired compound are collected, and chloroform is distilled off under reduced pressure to give the title compound (0.71 g). m.p.: 143°-144° C. (amorphous) IR (KBr; cm-1): 1725, 1690, 1635
