Versuchsvorschrift
A synthetic reaction scheme for the preparation of6-methyl-4-phenyl-3-(4-pyrimidin-2-ylpiperazin-1-yl)pyridazine (MW01-7-057) is depicted in FIG. 26, and synthesis was carried out as described herein. A mixture of 3-chloro-6-methyl-4-phenylpyridazine (100 mg, 0.5 mmol), 1-(2-pyrimidyl)piperazine (400 mg, 2.0 mmol) in 3 ml of 1-BuOH was heated with stirring at 130 C for 7 days. 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 give, light yellow solid (68 mg, 0.20 mmol, yield 41.7%). Purity>95%; ESI-MS: m/z 333.1 (M+H+). 1H NMR (CDCl3): d 8.310 (d, J=5.0, 2H), 7.678 (d, J=7.5, 2H), 7.476 (m, 3H), 7.119 (s, H), 6.509 (t, J=4.5, 1H), 3.785 (t, J=4.5, J=5.0, 4H), 3.277 J=4.5, J=5.0, 4H), 2.669 (s, 3H).
