Reaction Steps

205 mg of 2-bromoaniline and 72 mg of anhydrous magnesium sulfate are suspended in 7 ml dimethylacetamide. 325 mg of 1-[6-(4-Hydroxy-3,5-dimethyl-phenyl)-3-methoxy-pyridazin-4-yl]-ethanone and 86.6 μl acetic acid are added and the reaction is degassed with argon. 330 mg of tripotassium phosphate and 61 mg of bis(tri-tert-butylphosphine) palladium (0) are added and the reaction is degassed with argon. The reaction is heated to 140° C. for 5 h. The solution is poured into water and extracted with ethyl acetate. The solvent is removed under reduced pressure. The product is purified by silica gel chromatography, eluting with a gradient of ethyl acetate in heptane. Yield 105 mg. LC-MS (ES+) 346 (M+H)+.
