  Investigations on the preparative methods and some chemical modifications of the previously reported potent diuretic, 1, 4-dimorpholino-7-phenylpyrido [3, 4-d] pyridazine (1 : DS-511) were undertaken, producing a variety of derivatives shown in Table I. Comparison of the reactivity between the two chloro groups in 1, 4-dichloropyrido [3, 4-d] pyridazine showed that the 4-chloro group is more reactive toward nucleophilic substitution than the 1-chloro group. Some reaction of 1, e. g. acid hydrolysis, reduction and Grignard addition reaction were also carried out. Significance of the ring nitrogen at the 6-position in 1 for diuretic activity is discussed.

  对之前报道的强效利尿剂 1，4-二吗啉基-7-苯基哒嗪[3，4-d] （1 : DS-511）的制备方法和一些化学修饰进行了研究，制备出了表 I 所示的多种衍生物。对 1，4-二氯哒嗪[3，4-d]中两个氯基的反应性进行比较后发现，4-氯基对亲核取代的反应性比 1-氯基强。还对 1 进行了一些反应，如酸水解、还原和格氏加成反应。讨论了 1 中位于 6 位的环氮对利尿活性的重要意义。
