実験手順

DIPEA (4.00 mL, 22.90 mmol) was added to a solution of 3-iodo-4-methylbenzoic acid (2 g, 7.63 mmol) and 2-(6-chloro-1H-benzotriazole-1-yl)-1,1,3,3-tetramethylaminium hexafluorophosphate (HCTU, 3.47 g, 8.40 mmol) in THF (18 mL) and NMP (2 mL) and the RM was stirred at RT for 30 min. 4-(Trifluoromethoxy)aniline (1.536 mL, 11.45 mmol) was then added and the RM was stirred at RT for 14 h. The solvent was evaporated off under reduced pressure and the residue was treated with aq. 1M HCl (50 mL) and extracted with TBME. The combined extracts were washed with aq. 1 M HCl (50 mL), aq. sat. Na2CO3, water, brine, dried over MgSO4 and the solvent was evaporated off under reduced pressure to give a residue which was crystallized from n-heptane/EtOAc to afford the title compound as white needles. UPLC-MS (Condition 1) tR=3.42 min, m/z=421.9-422.9 [M+H]+, m/z=419.9-420.9 [M−H]−; 1H-NMR (400 MHz, DMSO-d6) δ ppm 2.44 (s, 3H) 7.36 (d, J=8.3 Hz, 2H) 7.49 (d, J=8.3 Hz, 1H) 7.83-7.93 (m, 3H) 8.39 (d, J=2.0 Hz, 1H) 10.42 (s, 1H).
