Participants

Reaction Steps

The compounds as identified in Table 15 were prepared in the synthetic manner and after-treatment similar to those in Example 8 except that the 4,5-dichloro-2-alkyl- 3(2H)pyridazinones with R1 and R2 as identified in Table 15 were used instead of the starting 4,5-dichloro-2-t-butyl-3(2H)pyridazinone used in Example 8, and the N-alkylbenzylamines with R3, Y1, Y2 and Y3 as identified in Table 15 were used instead of the starting 4-di-n-propylaminomethyl-N-methylbenzylamine. In the NMR data, only the characteristic absorptions are given in Table 15.
