Water → 1-Benzyl-4-(4-nitrophenyl)piperazine

참여 물질

반응 단계

1-Benzylpiperazine (2.8 ml; 16 mmol) and potassium carbonate (2.3 g; 17 mmol) were added to a solution of 1-chloro-4-nitrobenzene (2.0 g; 13 mmol) in dimethylformamide (0.5 ml), and the mixture was stirred for 7 hours in a bath controlled at 100° C. Water was added to the reaction mixture to conduct extraction with chloroform. The organic layer was washed with saturated brine, dried over anhydrous sodium sulfate and then concentrated under reduced pressure. The resultant crude oil was purified by column chromatography on silica gel, thereby obtaining 2.9 g (yield: 76%) of 4-(4-benzyl-1-piperazinyl)-1-nitrobenzene as a colorless oil.
