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. 38024-35-0, 4-Aminocinnoline-3-carboxamide. This 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.38024-35-0
To a suspension of 4-aminocinnoline-3-carboxamide (3.5 g, 18.60 mmol) in DCM (10 ml) was added POCI3 (43.3 ml, 465 mmol) followed by triethylamine (7.78 ml, 55.8 mmol). The mixture was refluxed for 7 h. The reaction was then allowed to cool to 11 and conc, in vacuo. The crude residuewas then carefully treated with saturated aqueous NaHCO3 at 0 C. A precipitate formed which was collected via vacuum filtration. The filter cake washed with water (-i00 ml,), collected, and driedvacuo to provide the title compound as a grey solid 4-aminocinnoiine-3-carbonitriie., 38024-35-0
The chemical industry reduces the impact on the environment during synthesis, 38024-35-0, , I believe this compound will play a more active role in future production and life.
