Extracurricular laboratory: Synthetic route of 3-Bromo-2-chloro-6-picoline

While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 185017-72-5, 3-Bromo-2-chloro-6-picoline.

Synthetic Route of 185017-72-5, 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. 185017-72-5, name is 3-Bromo-2-chloro-6-picoline, molecular formula is C6H5BrClN, 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.

To a solution of 3-bromo-2-chloro-6-methylpyridine (60 mg, 0.291 mmol) in DMA (2 mL) was added 2- (cyclopentyldifluoromethyl) oxazole (50 mg, 0.267 mmol) , KOAc (55 mg, 0.560 mmol) and Pd (PPh3)4(30 mg, 0.026 mmol) under N2atmosphere and the mixture was stirred at 80 overnight. Then the mixture was cooled to rt, filtered and the filtrate was concentrated in vacuum, the residue was purified by prep. TLC (EA: PE5: 1) to give the title compound. MS: 313 (M+1) .

While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 185017-72-5, 3-Bromo-2-chloro-6-picoline.
