Participants

Reaction Steps

Methanesulphonyl chloride (1.0 ml) was added to a stirred suspension of 7-cyano-3-hydroxy-1-methyl-4quinolone (0.4 g) and triethylamine (2.0 ml) in dry dichloromethane (200 ml) at 0 to 5° and the resultant solution stirred for 2 hours. The solution was washed with water (2×50 ml), dried over magnesium sulphate and the solvent removed by distillation. The residue was purified by flash chromatography on a silica gel column eluted with dichloromethane:methanol (40:1) followed by trituration with diethyl ether (10 ml) to give the novel compound 7-cyano-1-methyl-4-oxo-1,4-dihydroquinol-3-yl methanesulphonate, m.p. 268°.
