2-Cyanopiperazine represented by the following formula (1): ##STR1## or a salt thereof. The 2-cyanopiperazine can be produced by reacting a 2-halogenoacrylonitrile with ethylenediamine or by reacting a 2,3-dihalogenopropionitrile with ethylenediamine. The 2-cyanopiperazine is useful as an intermediate for medicaments, agricultural chemicals, etc., and optically active N-tert-butyl-2-piperazine carboxamide, which is useful as an intermediate in preparation of the HIV protease inhibitor indinavir, can be easily produced using the 2-cyanopiperazine.
2-氰基哌嗪由以下化学式(1)代表:##STR1##或其盐。2-氰基哌嗪可通过将2-卤代丙烯腈与乙二胺反应或将2,3-二卤代丙烯腈与乙二胺反应而制得。2-氰基哌嗪可用作药物、农药等的中间体,并且可使用2-氰基哌嗪轻松制备出对光学活性的N-叔丁基-2-哌嗪羧酰胺,后者在制备HIV蛋白酶抑制剂洛匹那韦的中间体时非常有用。
