m-Chloroperbenzoic acid → HCID 17979838, compound

Participants

Reaction Steps

A solution of 46 g of m-chloroperbenzoic acid in 19 ml of dichloromethane is added dropwise to a solution of 17.6 g of 6-methyl-3-nitroquinoline (compound E2) in 400 ml of dichloromethane. The reaction mixture is stirred for 70 h, diluted with 20 ml of dichloromethane and extracted two times each with 800 ml of halfsaturated aqueous sodium hydrogencarbonate solution. The organic layer is dried over magnesium sulfate, filtered and evaporated in vacuo. The residue is chromatographed on silica gel (dichloromethane/methanol 98:2). 8.25 g of the title compound are obtained as yellow crystals.
