Participants

Reaction Steps

Triethylamine (5.6 ml) was added to a stirred suspension of 1-ethyl-3-hydroxy-4-quinolone (3.74 g) and methanesulphonyl chloride (2.3 ml) in dichloromethane (80 ml) and the resultant solution was stirred for 90 minutes. The solution was washed with water (50 ml) and dried over magnesium sulphate. The solvent was removed by distillation and the residue crystallised from industrial methylated spirit (10 ml) to give the novel compound 1-ethyl-4-oxo-1,4-dihydro-quinol-3-yl methanesulphonate, m.p. 141°-143°.
