Benzene → 2-(4-Methylpiperazin-1-yl)propanenitrile

Participants

Reaction Steps

Lactonitrile (71.08 g.) is added in a dropwise manner to a stirred solution of 100.1 g. of 1-methyl-piperazine in 500 ml. of benzene. The resulting warm solution is heated at reflux under a water separator until the theoretical amount of water is collected (about 4 hours). The solution is evaporated at reduced pressure and the residue is fractionated. The product, 2-(4-methyl-1-piperazinyl)propionitrile, is obtained as an oil, b.p. 128°-130° C./23 mm.
