실험 절차

A mixture of {4-[(2,3-dihydro-1H-inden-2-ylamino)methyl]-3,5-difluoro-phenyl}boronic acid (740 mg, 2.44 mmol; Ex V-22), 3-bromonitrobenzene (495 mg, 2.44 mmol), PdCl2(dppf)2 (100 mg, 0.12 mmol) and Na2CO3 (4.90 mL, 2.0 M (aq)) in DME (10 mL) was stirred at 80° C. for 45 min. The mixture was diluted with EtOAc then filtered through a pad of Celite and silica gel. The filtrate was washed with H2O and brine, dried over Na2SO4 then concentrated to give N-[(3,5-difluoro-3′-nitro-4-biphenylyl)methyl]-2,3-dihydro-1H-inden-2-amine as a tan glass. LC/MS (method A) 0.62 min, (m/z) 381 (70%), 382 (100%).
