As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 886365-06-6, name is Methyl 5-bromo-4-methylpicolinate, molecular formula is C8H8BrNO2, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below. Computed Properties of C8H8BrNO2
Step 1 To a solution of 5-bromo-4-methylpyridine-2-carboxylic acid methyl ester (2.207 g, 9.59 mmol), 4-methoxylphenylboronic acid (1.604 g, 10.55 mmol) and 1,1′-bis(di-tert-butylphosphino)ferrocene palladium dichloride (0.313 g, 0.480 mmol) in THF (30 mL) was added potassium carbonate (2.0 M in water, 10.1 mL, 20.15 mmol). The mixture was purged with nitrogen and heated at 50 C. for 1 hour and at 60 C. for 5 hours. The reaction was poured into ethyl acetate and was washed with brine, dried over sodium sulfate, filtered and concentrated. It was purified by column chromatography to yield methyl 5-(4-methoxyphenyl)-4-methylpyridine-2-carboxylate (2.47 g, 9.59 mmol) as a pink solid. MS ESI calc’d. for C15H16NO3 [M+H]+ 258.1. found 258.1.
With the rapid development of chemical substances, we look forward to future research findings about 886365-06-6.
