    YieldReaction ConditionsOperation in experiment
    25% With sulfuric acid; sodium 3-nitrobenzenesulfonate In water at 120 - 130℃; for 1.5 h; The raw materials 3,5-difluoroaniline G-1 (5.6 g, 27 mmol) and sodium 3-nitrobenzenesulfonate (7.2 g, 32 mmol) Was added to a mixed solution of concentrated sulfuric acid (15 mL) and water (6 mL) After heating to an internal temperature of 120 ° C, glycerol (7.4 g, 80 mmol) After the addition was completed, the temperature was raised to 130 ° C and reacted for 1.5h, then cooled. The reaction was poured into crushed ice, concentrated ammonia water to adjust the pH to 5 ~ 6, the precipitated solid was filtered off, washed with water, After drying, column chromatography gave 3.82 g of white solid compound G-2 in 58percent yield. A mixture of 6-bromo-7-methylquinoline (I-2) and 6-bromo-5-methylquinoline (J-1) was synthesized. Then separated by supercritical preparative chromatography (SFC), IC-H column, mobile phase: isopropanol / carbon dioxide = 18/82, detection wavelength: 254nm. The first fraction was collected as 6-bromo-7-methylquinoline (I-2) as a white solid, yield: 25percent. The second fraction was collected as a 6-bromo-5-methylquinoline (J-1) white solid in a yield of 20percent

    Stage #1: With iron(III) sulfate; sulfuric acid In nitrobenzene for 3 h; Heating / reflux
    Stage #2: With water; sodium hydrogencarbonate In nitrobenzene
    Intermediate 4: 6-Bromo-7-methyl-quinoline; [0304] A mixture of 4-bromo-3-methylaniline (20 g, 107.5 mmol), ferric sulfate (6.6 g, 43.4 mmol), glycerol (40.8 g, 440 mmol), nitrobenzene (8.12 g, 66 mmol), and concentrated EPO <DP n="81"/>sulfuric acid (23 ml) was heated gently. After the first vigorous reaction, the mixture was boiled for 3h and then evaporated to remove the excess nitrobenzene. The solution was added a saturated aqueous solution of sodium bicarbonate until pH=7-8, then the solution was filtered and extracted with dichloromethane. The combined organic layers were dried over Na2SO4, filtered and concentrated in vacuo. The solid was purified by flash column chromatography to give a yellow solid, which was further washed with petroleum ether to give 7.5 g of 6-bromo-7-methyl-quinoline (31percent yield): 1H NMR (CDCl3): 2.60 (s, 3H), 7.36 (m, IH), 7.96 (s, IH), 8.04 (m, 2H), 8.89 (m, IH).
