Reaction Steps

A mixture of 6-amino-4-cyano-5,8-dimethylquinoline (2.0 g, 10.15 mmol), di-2-pyridyl thionocarbonate (2.52 g, 10.86 mmol), dimethylaminopyridine (0.266 g, 2.18 mmol) and methylene chloride (62 mL) is stirred at room temperature for 1.5 hours. Evaporation affords a residue which is purified by chromatography through a short column consisting of layers of sand/flash silica gel/sand, using methylene chloride as eluent, to give 4-cyano-5,8-dimethyl-6-isothiocyanatoquinoline.
