実験手順

3-Amino-4-benzyloxy-N-(3-cyclohexylphenyl)phenylacetamide (the compound of Example 33) (200 mg) is dissolved in pyridine (5 ml), and thereto is added dropwise methanesulfonyl chloride (111 mg), and the mixture is stirred for 0.5 hour. Water is added to the mixture, and the mixture is extracted with ethyl acetate. The organic layer is dried under sodium sulfate, and the solvent is evaporated under reduced pressure. The residue is purified by silica gel column chromatography (eluent: gradient from 0% to 100% hexane/ethyl acetate) to give 4-benzyloxy-N-(3-cyclohexylphenyl)-3-methanesulfonylaminophenyl-acetamide (200 mg). This product is dissolved in ethanol (10 ml), and thereto is added 10% palladium on carbon (20 mg). The mixture is subjected to catalytic hydrogenation at 25° C. The catalyst is removed by filtration, and the solvent is evaporated under reduced pressure. The residue is purified by silica gel column chromatography (eluent: gradient from 0% to 10% chloroform/methanol) to give the desired compound (120 mg).
