Synthetic Route of 17282-00-7 , The common heterocyclic compound, 17282-00-7, name is 3-Bromo-5-methylpyridin-2-amine, molecular formula is C6H7BrN2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
General procedure: Under N2 atmosphere, to a solution of palladium acetate (120 mg, 0.53 mmol, 5 mol %) and XANTPHOS (309 mg, 0.53 mmol, 5 mol %) in anisole (30 mL) was added 3-bromo-5-methyl-pyridin-2-ylamine (5) (2.0 g, 10.7 mmol, 1.0 equiv), aryl iodides (6) (10.7 mmol) and cesium carbonate (4.9 g, 15.0 mmol, 1.4 equiv), and the mixture was stirred at 130 C for 1-13 h. After cooling to room temperature, water (40 mL) was added to the mixture. The mixture was concentrated in vacuo and ethyl acetate (100 mL) was added to the residue. The organic layer was washed with water (20 mL) and concentrated in vacuo to give the crude product, which was purified by flash chromatography to give 7.
The synthetic route of 17282-00-7 has been constantly updated, and we look forward to future research findings.
