실험 절차

A solution of 2-(4-bromo-3-fluorophenyl)acetic acid (50 mg, 0.215 mmol), 4-(3-((tert-butyl dimethylsilyl)oxy)-2,2-dimethylpropyl)-3-(trifluoromethyl)aniline (78 mg, 0.215 mmol), N-ethyl-N-isopropylpropan-2-amine (83 mg, 0.644 mmol), 1H-benzo[d][1,2,3]triazol-1-ol hydrate (49.3 mg, 0.322 mmol) and N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (61.7 mg, 0.322 mmol) in DCM (20 mL) was stirred at 20° C. for 16 h. The mixture was washed with H2O (20 mL) and brine (20 mL). The organic layer was dried over Na2SO4, filtered and concentrated. The crude material was purified by preparative TLC (PE/EA=3/1) to yield 2-(4-bromo-3-fluorophenyl)-N-(4-(3-((tert-butyldimethylsilyl)oxy)-2,2-dimethylpropyl)-3-(trifluoromethyl)phenyl)acetamide (80 mg, 0.132 mmol, 61.4% yield): 1H NMR (400 MHz, CD3OD) δ 7.83 (d, J=2.0 Hz, 1H), 7.61 (d, J=6.6 Hz, 1H), 7.49 (t, J=7.7 Hz, 1H), 7.35 (d, J=8.6 Hz, 1H), 7.15 (dd, J=9.7, 1.8 Hz, 1H), 7.01 (d, J=6.8 Hz, 1H), 3.62 (s, 2H), 2.70 (s, 2H), 2.07 (s, 2H), 0.86 (s, 9H), 0.76-0.69 (m, 6H), 0.05-0.02 (m, 6H); ES-LCMS m/z 576.0 (M+H).
