Reaction Steps
To a solution of 5-chloro-6-methyl-1,2,4-triazin-3-amine (2.00 mmol) in 8 mL toluene is added 4-(dimethylphosphoryl)-2-(propan-2-ylsulfonyl)aniline (2.20 mmol), palladium acetate (22.4 mg, 0.0100 mmol), XANTPHOS (69.4 mg, 0.120 mmol), and cesium carbonate (2.20 mmol). The mixture is purged with nitrogen, and can be subjected to microwaves at 100° C. until formation of the desired product. The reaction mixture can then be concentrated and purified by silica gel chromatography.
