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.
通过在存在酸受体的情况下,将2-羟基嘧啶酸盐与烷磺酰氯反应,制备新型的2-嘧啶基烷磺酸酯。这些新型的2-嘧啶基烷磺酸酯可优势地用于与新型的1-(氰基烷基)哌嗪在存在酸受体的情况下反应,制备1-(氰基烷基)-4-(2-嘧啶基)哌嗪。
