反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 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. The reaction mixture was washed with brine the organics separated, dried over magnesium sulfate concentrated

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Added together 2-methylphenyl boronic acid (24.7 g, 181 mmol), 2-bromo aniline (25.7 g, 151 mmol), palladium(II)acetate (0.85 g, 3.78 mmol), triphenylphosphine (4.0 g, 15.1 mmol), a 2 M solution of potassium carbonate (204 mL) and ethylene glycol dimethyl ether (223 mL) and heated the reaction mixture at reflux for 18 hours. After the reaction was cooled to room temperature, the aqueous phase was separated from the organic phase. The aqueous phase was extracted with ethyl acetate and the organic extractions were combined, dried over magnesium sulfate and filtered. The crude product was purified by silica gel column chromatography using 10% ethyl acetate in hexanes as the eluants. The pure fractions were collected, combined and concentrated to give 2-amino-2′-methyl-biphenyl (23.5 g, 84.8% yield) whose structure was confirmed by GCMS and NMR. at reflux for 18 hours the aqueous phase was separated from the organic phase The aqueous phase was extracted with ethyl acetate the organic extractions dried over magnesium sulfate filtered The crude product was purified by silica gel column chromatography The pure fractions were collected concentrated
