A process for producing an azacycloalkane derivative represented by the following general formula (II): ##STR1## wherein m is an integer of from 1 to 3, n.sub.2 is an integer of from 2 to 10, and R represents an alkyl group having 3 to 12 carbon atoms, characterized by reacting a 1-(n-alkenyl)-azacycloalkan-2-one represented by the following general formula (I): ##STR2## wherein m is an integer of from 1 to 3, and n.sub.1 is an integer of from 0 to 8, with an alkyl mercaptan in the presence of a radical initiator in an organic solvent, treating the reaction mixture thus obtained with a reducing agent in a water-containing organic solvent, and then purifying the treated mixture by distillation.
一种生产以下一般式(II)所代表的氮杂环烷衍生物的方法:其中m是1到3的整数,n.sub.2是2到10的整数,R代表具有3到12个碳原子的烷基基团,其特征在于,在有机溶剂中,在存在自由基引发剂的情况下,将以下一般式(I)所代表的1-(n-烯烃基)-氮杂环烷-2-酮与烷基硫醇反应,其中m是1到3的整数,n.sub.1是0到8的整数,然后在含水有机溶剂中用还原剂处理得到的反应混合物,然后通过蒸馏纯化所处理的混合物。
