実験手順

To a solution of N1-(4-methoxybenzoyl)-4-(tert-butyldimethylsilyloxy)-1,2-benzenediamine (300 mg, 0.81 mmol) in methylene chloride (20 mL) was added pyridine (0.13 mL, 1.6 mmol) followed by 4-propylbenzoyl chloride (0.15 mL, 0.89 mmol). The reaction mixture was stirred for 4 h, diluted with methylene chloride, washed with saturated aqueous cupric sulfate solution, dried (magnesium sulfate), filtered, and concentrated in vacuo. The residue was chromatographed (silica gel, methylene chloride to 20% ethyl acetate/80% methylene chloride) to give 400 mg (95%) of the the title compound as a solid.
