実験手順
Added 2-amino-3′,5-di-t-butyl biphenyl (2.0 g, 7.11 mmol) to a solution of formic acid and heated to reflux for 16 hours. After cooling, water (25 mL) was added the product and the precipitate collected by vacuum filtration. The crude product was dissolved into ethyl acetate, washed with water. The organics were dried over magnesium sulfate and concentrated and purified by column chromatography using 10% ethyl acetate and hexanes as the eluants to give the pure N-formyl-2-amino-3′,5-di-t-butyl biphenyl (1.8 g, 82% yield) as determined by GCMS.
