Novel cyanoalkylpiperazines are prepared by reacting piperazine with a haloalkylnitrile in the presence of an acid acceptor. The novel cyanoalkylpiperazines are advantageously employed to prepare 1-(cyanoalkyl)-4-(2-pyrimidyl)piperazines by reacting them with halopyrimidines in the presence of an acid acceptor.
