反応手順
68 g (0.3 mol) of 2,4,5-Trichloronitrobenzene and 77.4 g (0.9 mol) of piperazine were stirred in 100 ml of a dimethylformamide in the presence of 31 g of anhydrous potassium carbonate for one hour at a room temperature of 25° C. to 40° C. and then for one hour at 70° to 80° C. to obtain 49.5 g of 2-piperazino-4,5-dichloronitrobenzene. This compound was reacted with 2-ethylhexanoyl chloride in a solvent of acetonitrile in the presence of pyridine to obtain 2-[N-(2-hexanoyl)piperazino]-4,5-dichloronitrobenzene.
