Abstract
Attempts to prepare 5, 6-dihydropyrido[2, 3-d]pyridazin-8(7H)-one by the hydrogenation of pyrido[2, 3-d]pyridazin-8(7H)-cne were not successful, but it was found that the hydrogen-ated compound was 1, 2, 3, 4-tetrahydropyrido[2, 3-d]pyridazm-8(7H)-one. The same reaction occurred in the case of pyrido[2, 3-d]pyridazin-5(6H)-one and some other derivatives.
