The solvent was removed by evaporation in vacuo, the residue was treated with water to give a suspension. The solid was then filtered off, washed with water, then 1:3, Ethyl Acetate:Petroleum ether, dried over filter funnel in vacuo to yield a gray solid. ESI-MS: m/z 362.2 (M+H+). A synthetic reaction scheme for the preparation of 3-(4-methylpiperazin-1-yl)-N-(2-morpholinoethyl)-6-phenyl-4-(pyridin-4-yl)pyridazin-3-amine (MW01-7-091WH) is depicted in FIG. 10.
