Procedure

The above compound, 2-amino-2′-methyl-biphenyl (11.0 g, 60 mmol) was added to dry toluene (250 mL) containing triethyl amine (24 g, 24 mmol) and stirred under a nitrogen pad. Ethyl chloroformate (26 g, 240 mmol) was slowly added to the stirred solution via a syringe. The reaction mixture was washed with brine and the organics separated, dried over magnesium sulfate and concentrated to give N-ethoxycarbonyl-2-amino-2′methyl biphenyl as a colorless oil (7.0 g, 46% yield) whose structure was confirmed by GCMS and NMR.
