To a suspension of 6-bromonicotinoyl chloride (0.5 g, 2.5 mmol) in dry chloroform (10 mL) was added 4-fluoroaniline (0.33 mL, 3.5 mmol) and 2-ethyoxy-1-ethoxycarbonyl-1,2-dihydroquinoline, (0.85 g, 3.5 mmol). The mixture was stirred for 12 h, diluted with hexanes and the solids isolated by filtration. Purification by trituration using ethyl acetate/hexanes gave 0.53 g (73%) of the desired product as a white solid. 1H NMR (300 MHz, DMSO-d6) δ 10.51 (s, 1H), 8.87 (m, 1H), 8.20 (m, 1H), 7.82 (m, 1H), 7.74 (m, 2H), 7.19 (m, 2H).
