실험 절차

A mixture of 7-amino-5-fluoro-8-methylquinoline (0.39 g) and thiophosgene (0.2 mL) in water (5 mL) and 1N hydrochloric acid (5 mL) is stirred at room temperature for 1.5 hours. An additional amount of thiophosgene (0.1 mL) is added and the mixture stirred another hour. The mixture is treated with 1N sodium hydroxide (25 mL) and extracted with methylene chloride (4×50 mL). The combined extracts are dried over sodium sulfate and rotary evaporated. The residue is purified by flash chromatography on silica gel, eluting with 15% ethyl acetate/hexane, to afford 5-fluoro-8-methyl-7-quinolinylisothiocyanate as a tan solid.
