As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 886365-06-6, name is Methyl 5-bromo-4-methylpicolinate, the common compound, a new synthetic route is introduced below. Formula: C8H8BrNO2

(2-Fluoro-4-methoxyphenyl)boronic acid (177 mg, 1.043 mmol), methyl 5-bromo-4- methylpyridine-2-carboxylate (200 mg, 0.869 mmol), 1,3 bis(di-tert-butylphosphino)ferrocene palladium dichloride (89 mg, 0.130 mmol), cesium carbonate (623 mg, 1.913 mmol) and THF (5 mL) were sealed in a microwave vessel and subject to microwave irradiation at 140 C for 20 min. The reaction crude was combined with the crude from an identical probe reaction (44.3 mg scale). Volatiles were removed under reduced pressure. The resulting pot residue was purified by preparative HPLC (reverse phase, Kromasil 100-5C18, 100×21.1 mm) eluting with acetonitrile/water + 0.1% TFA (30% to 100% organic in 10 min, then to 100% for 2 min, 20 mL/min). Related fractions were pooled and evaporated under reduced pressure to afford a dark solid. This solid was further purified by flash chromatography (Si02, Biotage SNAP Cartridge, silica gel, KP-Sil, 50 g cartridge). The column was eluted with an EtOAc hexanes mixture (0% to 100%). Related fractions were pooled and evaporated to afford a light yellow oil as the titled compound. LCMS calc. = 275.10; found = 276.11 (M+H)+.

This compound has unique chemical properties. The synthetic route is as follows. COA of Formula: C8H8BrNO2

Into a vial was weighed methyl 5-bromo-4-methylpicolinate (1.00 g, 4.35 mmol), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II)-dichloromethane complex (181 mg, 0.217 mmol), bis(pinacolato)diboron (1.21 g, 4.78 mmol), and potassium acetate (1.28 g, 13.0 mmol). Under nitrogen, anhydrous 1,4-dioxane (11 mL) was added and the vial was sealed. The reaction mixture was stirred at 100 C. for 18 h. After cooling to rt, the reaction mixture was concentrated and the residue purified by flash column chromatography (CH2Cl2/MeOH, 100:0-90:10) to afford 756 mg of crude aryl pinacolboranate intermediate (contaminated with pinacolborane by 1H NMR). Combining this intermediate (323 mg, ?1.17 mmol) with (+-)-(1S,2S)-N-(8-(bis(2,4-dimethoxybenzyl)amino)-6-chloro-2,7-naphthyridin-3-yl)-2-(1-methyl-1H-pyrazol-4-yl)cyclopropane-1-carboxamide (500 mg, 0.777 mmol), chloro(2-dicyclohexylphosphino-2′,4′,6′-triisopropyl-1,1′-biphenyl)[2-(2′-amino-1,1′-biphenyl)]palladium(II) (32.8 mg, 0.0389 mmol), 2-dicyclohexylphosphino-2′,4′,6′-triisopropylbiphenyl (18.9 mg, 0.0389 mmol), and potassium phosphate tribasic monohydrate (554 mg, 2.33 mmol) in a vial, tetrahydrofuran (3.9 mL) and water (0.7 mL) were added under nitrogen and the vial was sealed and stirred at 80 C. for 19 h. The reaction mixture still contained starting material and so an equal aliquot of catalyst, ligand and water, as well as potassium phosphate tribasic monohydrate (184 mg, 0.777 mmol) and crude aryl pinacolboranate (215 mg, ?0.77 mmol) were added and stirred at 80 C. for 3 days. The mixture was concentrated to dryness and residue purified by flash column chromatography (CH2Cl2/MeOH, 100:0-90:10). The crude compound thus obtained was a yellow oil that contained the product according to HPLC-MS.
