실험 절차

A mixture of 2-ethyl-N-(3-fluoro-4-piperazin-1-yl-phenyl)-butyramide dihydrochloride (0.26 g, 0.70 mmol), bromo-(3-fluoro-phenyl)-acetic acid methyl ester (0.23 g, 0.91 mmol), and anhydrous K2CO3 (0.34 g, 2.45 mmol) in DMF (10 mL) was stirred for 20 h. The mixture was diluted with water (100 mL) and extracted with DCM (2×30 mL). The combined organic layers were washed with water, dried (Na2SO4), and concentrated. The residue was purified (SiO2; acetone/DCM) to give the title compound (0.25 g, 78%). MS: mass calcd. for C25H31F2N3O3, 459.23. m/z found, 460.3 [M+H]+. 1H NMR (CDCl3): 7.48-7.43 (m, 1H), 7.35-7.28 (m, 1H), 7.25-7.20 (m, 2H), 7.17 (br s, 1H), 7.12-7.07 (m, 1H), 7.05-6.99 (m, 1H), 6.86 (t, J=9.0, 1H), 4.07 (s, 1H), 3.71 (s, 3H), 3.11-3.04 (m, 4H), 2.70-2.59 (m, 4H), 2.03-1.95 (m, 1H), 1.75-1.66 (m, 2H), 1.59-1.49 (m, 2H), 0.93 (t, J=7.4, 6H).
