実験手順

The procedures in Synthesis Example 2 were repeated by using 2.0 g (7.2 m mol) of 2-(4-chlorophenyl)-4,5-dichloro-3(2H)-pyridazinone, 1.1 g (7.7 m mol) of 6-chloro-3-pyridine methanol, 0.4 g of potassium hydroxide and 80 ml of N,N-dimethylformamide to give 1.7 g of the intended product (recrystallized from benzene/n-hexane).
