Electric Literature of 65515-28-8, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.65515-28-8, name is Methyl 2,6-dichloronicotinate, molecular formula is C7H5Cl2NO2, molecular weight is 206.03, as common compound, the synthetic route is as follows.
step 1 (S ) -6-chloro-2- [1- (4-fluorophenyl) ethylamino] methyl nicotinatewas dissolved 2,6-dichloro-nicotinic acid methyl ester 5.0 g N, the N- dimethylformamide 50 ml, (S) – (-) – 1- (4-fluorophenyl) ethylamine 4.39 g, N, N-diisopropylethylamine 6.27g and 4-dimethylaminopyridine 150mg was added, and stirred for 24 hours at 60 C..The reaction mixture was cooled, diluted with ethyl acetate, washed successively with water and saturated brine, and dried over magnesium sulfate.Under reduced pressure, the solvent was distilled off, the resulting residue was purified by silica gel column chromatography to give the title compound 2.83g as a white powder.
Statistics shows that 65515-28-8 is playing an increasingly important role. we look forward to future research findings about Methyl 2,6-dichloronicotinate.
