Abstract
Novel 1-(cyanoalkyl)-4-guanylpiperazine acid salts are prepared by reacting novel 1-(cyanoalkyl)piperazines with cyanamide in the presence of an acid. The novel 1-(cyanoalkyl)-4-guanylpiperazine acid salts are advantageously employed to prepare 1-(cyanoalkyl)-4-(2-pyrimidyl)piperazines by reacting them with malonaldehyde in an acidic medium.
