Methyl iodide → HCID 19592958, compound

Participants

Reaction Steps

To a solution of 4-(2-acetyl-2-methylhydrazino)-8-(2,6-dichlorobenzoylamino)quinoline (140 mg) in N-methylpyrrolidone (1.5 ml) was added potassium tert-butoxide (40.9 mg) under ice-cooling, and the mixture was stirred for 30 minutes at the same temperature. Methyl iodide (59.1 mg) was added thereto under ice-cooling, and the mixture was stirred for 12 hours at ambient temperature. The mixture was diluted with ethyl acetate, washed with water and brine, dried over magnesium sulfate and evaporated in vacuo. The residue was purified by preparative thin layer chromatography (methanol-dichloromethane) and recrystallized from ethanol to give 4-(2-acetyl-1,2-dimethylhydrazino)-8-(2,6-dichlorobenzoylamino)quinoline (62 mg).
