Participants

Reaction Steps

To a mixture of 6-chloro-1-(2,4-dichlorobenzo-yl)-2,3-dihydro-4(1H)-quinolinone-4-oxime (10.0 g), triethylamine (4.1 g) and dichloromethane (150 ml) was added dropwise methanesulfonyl chloride (3.5 g) at -20° C. with stirring. The mixture was stirred at -20° C. for 30 minutes and dichloromethane (300 ml) was added. The reaction mixture was sequentially washed with 1 N HCl, saturated aqueous sodium bicarbonate solution, then with saturated aqueous NaCl solution and dried over anhydrous sodium sulfate. Solvent was removed in vacuo and the residue was recrystallized with ether and n-hexane to obtain 6-chloro-1-(2,4-dichlorobenzoyl)-2,3-dihydro-4(1H)-quinolinone-4-oxime mesylate (yield 11 g) as white crystal.
