실험 절차

To (2S)-2-[(4-bromobenzyl)amino]-N-(cyanomethyl)-4-methylpentanamide (285 mg, 0.843 mmol) and 4-[4-(tert-butoxycarbonyl)-1-piperazinyl]phenylboronic acid (315 mg, 1.02 mmol) in DMF (10 mL) under dry nitrogen was added aqueous sodium carbonate (2 M, 1.3 mL, 2.53 mmol) followed by the catalyst PdCl2(dppf) (25 mg, 0.026 mmol). The reaction was heated to 95° C. for 0.5 hours and more PdCl2(dppf) (25 mg, 0.026 mmol) was added and the reaction mixture was heated overnight. Water was added and the product extracted with ether (2×), dried over Na2SO4, concentrated in vacuo, and purified by flash chromatography over silica gel (EtOAc/Hex, 4/6) to afford tert-butyl 4-(4′-{[((1S)-1-{[(cyanomethyl)amino]carbonyl}-3-methylbutyl)amino]methyl}[1,1′-biphenyl]-4-yl)-1-piperazinecarboxylate.
