Electric Literature of 1211518-35-2, 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. 1211518-35-2, name is Methyl 6-chloro-5-(trifluoromethyl)picolinate, molecular formula is C8H5ClF3NO2, 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.

Sodium hydride (1.1 g, 31.4 mmol) was added in portions to cyclopropylmethanol (20 mL) and the mixture was stirred at room temperature for 0.5 hours. 6-Chloro-5- (trifluoromethyl)-pyridine-2-carboxylic acid methyl ester (1.5 g, 6.3 mmol) was added and the resulting solution was stirred at 80C for 1 h. Water (20 mL) was added; the solution was acidified with 6 N hydrochloric acid and then concentrated to give a residue which was partitioned between water (30 mL) and ethyl acetate (20 mL). The aqueous solution was extracted with ethyl acetate (2 x 20 mL) and the combined organic phase was washed with brine (20 mL), dried over anhydrous sodium sulfate, filtered and concentrated to give the crude target compound. The crude target compound was purified by column chromatography (silica gel, 10 g, 15% ethyl acetate in petroleum ether) to give the title compound (1.4 g, 85%) as white solid; MS (EI): m/e = 262.0 [M+H]+.

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 1211518-35-2, Methyl 6-chloro-5-(trifluoromethyl)picolinate.
