Yield:40134-18-7 93%
Reaction Conditions:
with thionyl chloride for 8 h;Reflux;
Steps:
1.1 preparation of compound II
To the 250 ml flask is added in three 15.76g (0.1 μM) 2 - chloro -3 - picolinic acid, 100 ml methanol, under the ice-bath adds by drops 17.85g (0.15 μM) thionyl chloride, stirring and heating to reflux, the stirring reaction 8h. Thin layer chromatography tracking response, the raw materials point disappears, stopping the reaction. Reduced pressure distillation to remove the solvent to obtain light yellow 15.95g, yield 93%
