Abstract
Novel 2-pyrimidyl alkanesulfonates are prepared by reacting a 2-hydroxypyrimidine acid salt with an alkanesulfonyl chloride in the presence of an acid acceptor. The novel 2-pyrimidyl alkanesulfonates are advantageously employed to prepare 1-(cyanoalkyl)-4-(2-pyrimidyl)piperazines by reacting them with a novel 1-(cyanoalkyl)piperazine in the presence of an acid acceptor.
