実験手順
679 mg (3.91 mmol) of (3R)-1-azabicyclo[2.2.2]octane-3-carbonyl chloride, 846 mg (3.73 mmol) methyl 4′-amino-1,1′-biphenyl-4-carboxylate, 963 mg (7.45 mmol) of N,N-diisopropylethylamine and 227 mg (1.86 mmol) of 4-N,N-dimethylaminopyridine are dissolved in 5 ml of THF and stirred at RT overnight and then at 50° C. overnight once again. The reaction mixture is taken up in dichloromethane and water, and the aqueous phase is extracted three times with dichloromethane. The crude product is purified by chromatography on silica gel 60 (mobile phase: dichloromethane/triethylamine 100:1→dichloromethane/methanol/triethylamine 50:50:1). The solvent is removed under reduced pressure. The product is taken up in 1N sodium hydroxide solution and extracted a total of three times with ethyl acetate. The organic phase is dried over magnesium sulfate and freed of solvent under reduced pressure. Finally, the last residues of solvent are removed under high vacuum. 50 mg (4% of theory) of the title compound are obtained.
