Reaction Steps
Treat a N2 degassed mixture of tert-butyl 1-(6-chloro-4,5-dimethylpyridazin-3-yl)piperidin-4-yl(methyl)carbamate (3.01 g, 8.48 mmol), 4-fluorophenylboronic acid (1.23 g, 8.80 mmol) and CsF (4.08 g, 26.8 mmol) in 1,4-dioxane (80 mL) with (1,1′-bis(diphenylphosphino)ferrocene)palladium(II) chloride (1.10 g, 1.35 mmol). Heat the resulting mixture under N2 at 95° C. overnight. Partition the reaction mixture between H2O and EtOAc. Separate the layers, and wash the organic layer with brine. Dry the organic layer over Na2SO4, filter, and concentrate under reduced pressure. Purify the residue by flash silica gel chromatography (gradient of 20 to 80% EtOAc in hexanes) to provide the title compound (3.05 g, 87%). ES/MS m/z 415.2 (M+1).
