4-Bromo-3-(4H-1,2,4-triazol-3-yl)thiophen-2-amine (17 mg, 69.4 umol), 2-(3-fluoroquinolin-8-yl)acetic acid hydrogen chloride (22 mg, 91.0 umol), 2-chloro-1-methylpyridinium iodide (101 mg, 395 umol) and triethylamine (0.2 ml) in methylene chloride (1 ml) was heated to reflux. After stirring for 1 h, the solution was concentrated and the residue was purified by HPLC to yield N-(4-bromo-3-(1H-1,2,4-triazol-3-yl)thiophen-2-yl)-2-(3-fluoroquinolin-8-yl)acetamide. Method [7] retention time 5.67 min by HPLC (M+432 and 434) and (M+Na 454 and 456). 1H NMR (300 MHz, CDCl3) δ 12.25 (s, 1H), 8.83 (d, J=3.3 Hz, 1H), 7.87 (m, 2H), 7.80 (d, J=6.0 Hz, 1H), 7.73 (s, 1H), 7.66 (t, J=7.8 Hz, 1H), 6.90 (s, 1H), 6.70 (broad s, 2H), 4.56 (s, 2H).
