Adding a certain compound to certain chemical reactions, such as: 6937-03-7, Methyl 2-aminoisonicotinate, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, name: Methyl 2-aminoisonicotinate, blongs to pyridine-derivatives compound. name: Methyl 2-aminoisonicotinate
Example (Ik-129) 5-Chloro-2-({[1-methyl-3-(pentafluoroethyl)-4-(trifluoromethyl)-1H-pyrazol-5-yl]carbonyl}amino)isonicotinic acid 1.50 g (9.85 mmol) of methyl 2-aminoisonicotinate (commercially available) are stirred in 15 ml of dimethylformamide and admixed at a temperature of -18 C. in portions with 1.83 g (13.8 mol) of N-chlorosuccinimide. The mixture is then stirred for a further hour at -18 C. For work-up, the total reaction mixture is taken up in ethyl acetate and shaken against an aqueous sodium thiosulphate solution. The organic phase is then washed with water, dried over sodium sulphate and concentrated by evaporation in vacuo. The remaining residue is purified by means of column chromatography on silica gel using the eluent mixture cyclohexane:acetone (gradient). This gives 383 mg of methyl 2-amino-5-chloroisonicotinate (16%). 1H-NMR (400 MHz, d6-DMSO): delta=8.00 (s, 1H), 6.78 (s, 1H), 6.25 (br. s, 2H), 3.85 (s, 3H) ppm. HPLC-MSa): log P=1.30; mass (m/z)=187 [M+H]+.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,6937-03-7, Methyl 2-aminoisonicotinate, and friends who are interested can also refer to it.
