The compound as identified in Table 14 was prepared in the synthetic manner and after-treatment similar to those in Example 7 except that the 4-alkyl-5-chloro-2-alkyl-3(2H)pyridazinone with R1 and R2 as identified in Table 14 was used instead of the starting 4-ethyl-5-chloro-2-t-butyl-3(2H)pyridazinone used in Example 7, and the benzylamine derivative with R3, Y1, Y2 and Y3 as identified in Table 14 was used instead of the starting 4-methylbenzylamine. In the NMR data, only the characteristic absorptions were given in Table 14.
