반응 단계
A mixture of 2-(4′-chloro-5-trifluoromethanesulfonyloxy-3′-trifluoromethyl-biphenyl-3-yl)-4-methyl-pentanoic acid methyl ester (48 mg, 0.10 mmol), 3,5-bis-(trifluoromethyl)-aniline (18 μL, 0.12 mmol), sodium tert-butoxide (9.8 mg, 0.10 mmol), Pd(OAc)2 (2.5 mg, 0.01 mmol), 2-(di-tert-butylphoshino-1,1′-binaphthyl (3.5 mg, 0.01 mmol) and toluene (1 mL) was stirred under microwave irradiation at 130° C. for 3×10 min. The mixture was diluted with toluene (9 mL), washed with 1M HCl (2×10 mL) and brine (10 mL), dried (MgSO4), concentrated in vacuo and purified by flash column chromatography (diethylether-petroleum ether) to afford the title product as a colourless powder (28 mg, 44%). Mass spectrum (ESI, m/z): 610, 612 (M−H).
