The title compound was prepared from 5-amino-4-(thiazol-2-yl)thiophene-3-carbonitrile (271 mg, 1 mmol) and 2-(2-oxo-6-(trifluoromethyl)quinolin-1(2H)-yl)acetic acid (0.76 mmol) according to protocol A. The crude product was purified by column chromatography (35% EtOAc/hexanes) and HPLC to give N-(4-cyano-3-(thiazol-2-yl)thiophen-2-yl)-2-(2-oxo-6-(trifluoromethyl)quinolin-1(2H)-yl)acetamide (24.mg) as a white solid with an m/z of 461.1 and retention of 7.348 min using the [7] LCMS method. 1H-NMR (300 MHz, CDCl3) δ 13.21 (s, 1H), 7.93 (m, 2H), 7.86 (dd, J=8.9, 1.8 Hz, 1H), 7.58 (s, 1H), 7.54 (d, J=3.4 Hz, 1H), 7.46 (d, J=8.8 Hz, 1H), 7.31 (d, J=3.3 Hz, 1H), 7.00 (d, J=9.6 Hz, 1H), 5.35 (s, 2H). 13C-NMR (75 MHz, CDCl3) δ 165.3, 161.7, 161.0, 140.8, 140.0, 139.9, 129.4, 128.0, 126.5, 122.7, 120.4, 117.8, 115.9, 115.0, 114.7, 106.0, 46.3.
