Abstract
A novel process for preparing alkoxyalkylidenehydrazinopyridazine derivatives which comprises reducing a novel alkoxytriphenylmethylazopyridazine derivative, removing the triphenylmethyl group and reacting with an aldehyde or ketone derivative. A specific compound produced by this process is 3-[3-[[2-(3,4-dimethoxyphenyl)ethyl]amino]-2-hydroxypropoxy]-6-isopropylid enehydrazinopyridazine.
