1-(2-Pyridyl)piperazine Chemical Properties,Usage,Production

Chemical Properties

clear colourless to yellow liquid

Uses

1-(2-Pyridyl)piperazine is a compound that belongs to a class of selective α2-adrenoceptor antagonists. 1-(2-Pyridyl)piperazine shows sympatholytic activity. 1-(2-Pyridyl)piperazine is also a metaboli te of Azaperone (A802200).

Uses

1-(2-Pyridyl)piperazine was used to determine the aliphatic and aromatic isocyanates in air.

General Description

1-(2-Pyridyl)piperazine is a piperazine derivative.

Synthesis

110-85-0

109-04-6

34803-66-2

Step 1: 0.1 g (0.63 mmol) of 2-bromopyridine and 0.065 g (0.75 mmol) of piperazine were placed in a dry 5 mL microwave reactor protected by nitrogen and reacted at 150 °C for 20 min. After completion of the reaction, it was cooled to room temperature. Step 2: The reaction mixture was filtered using diatomaceous earth and the filter cake was washed with ethyl acetate. Step 3: The solvent was removed by distillation under reduced pressure to obtain the crude product. Step 4: Purification of the crude product by silica gel column chromatography with eluent ratio of dichloromethane:methanol=4:1 to obtain 1-(pyridin-2-yl)piperazine in 54% yield.
