実験手順

To a solution of biphenyl-3,4-diamine (0.99 mmol) in THF:MeOH:water (5 mL:10 mL:10 mL) was added cyanogen bromide (5M solution in acetonitrile, 1.06 mmol). The resulting mixture was stirred at room temperature overnight. The reaction was partitioned between EtOAc and aqueous sodium hydroxide and the aqueous layer re-extracted with EtOAc.
