63% With sodium; In tetrahydrofuran; REFERENCE EXAMPLE 6 7-Bromo-4-(2,4-dichloroanilino)-3-quinolinecarbonitrile A mixture of 2,4-dichloroaniline (1.213 g, 7.49 mmol) and sodium hyduide (300 mg of a 60% dispersion in oil, 7.50 mmol) in 50 rnL of tetrahydrofuran was heated at reflux for 15 minutes. The mixture was cooled, <strong>[364793-57-7]7-bromo-4-chloro-3-quinolinecarbonitrile</strong> (1.00 g, 3.75 mmol) was added and the mixture was heated at reflux for 30 minutes. After cooling to room temperature the reaction mixture was partitioned between ethyl acetate and water. The organic layer was dried over magnesium sulfate, filtered and concentrated in vacuo. The resultant solid was purified by flash silica gel chromatography eluding with 3:1 hexane: ethyl acetate to provide 927 mg (63% yield) of 7-bromo-4-(2,4-dichloroanilino)-3-quinolinecarbonitrile as a light yellow solid, mp 180-183OC; 1H NMR (DMSO-d6/tiifluoroacetic acid) a 7.53-7.65 (m, 1H), 7.83 (d, J=2 Hz, 1H), 7.93-7.99 (m, 2H), 8.13 (d, J=2 Hz, 1H), 8.53 (d, J=9 Hz, 1H), 8.83 (s, 1H); MS (ES) m/z 392, 394, 396 (M+1).
