実験手順

A solution of 4-(4′-nitrobiphenyl-2-carboxamido)-N-(2-benzyloxy-4-methylphenyl)-N-methylbenzamide (430 mg), 20% palladium hydroxide (80 mg) in methanol (20 ml) and 1,4-dioxane (30 ml) was stirred under atmospheric pressure of hydrogen at 30° C. After 5 hours, the reaction mixture was filtered through a bed of Celite, and the solvent was removed by evaporation and the crude product was purified by silica gel column chromatography (SiO2; 30 g, 3% methanol in chloroform) to give 4-(4′-aminobiphenyl-2-carboxamido)-N-(2-hydroxy-4-methylphenyl)-N-methylbenzamide (350 mg) as amorphous.
