Reaction Steps
A mixture of 2-amino-4-fluoro-6-nitrotoluene (4.4 g), glycerin (7.5 g), arsenic(V) oxide hydrate (Aldrich, 54% in arsenic, 5.0 g), and concentrated sulfuric acid (35 mL) is heated to 140° C. for 4 hours. The reaction is allowed to cool to room temperature and diluted with water (300 mL). The mixture is basified with concentrated ammonium hydroxide to pH=10 and extracted with ethyl acetate (6×300 mL). The combined extracts are dried over sodium sulfate and rotary evaporated. The crude product is purified by flash chromatography on silica gel, eluting with 25% ethyl acetate/hexane to afford 7-amino-5-fluoro-8-methylquinoline as a solid.
