Synthetic Route of 19847-12-2, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 19847-12-2 as follows.
General procedure: Sodium metal (23 mg) was dissolved in absolute methanol (20 ml) and was labeled as sodium methoxide solution in methanol. 2-Cyanopyridine (0.210 ml, 2 mmol) was dissolved in absolute methanol (10 ml) and to it was added sodium methoxide solution (0.5 ml) prepared above, the reaction contents were stirred at room temperature for 2 h. 4-(2-Aminoethyl) morpholine (0.26 ml, 2 mmol) was added to the reaction mixture. The reaction contents were heated under reflux for 8 h. Solvent was removed under reduced pressure and to the residue left behind was added diethyl ether, solid so obtained was filtered and washed with diethyl ether to give crude product. This crude product was purified by crystallization from ethyl acetate/methanol to give pure N-(2-morpholin-4-yl-ethyl)-pyridine-2-carboxamidine (3a).
According to the analysis of related databases, 19847-12-2, the application of this compound in the production field has become more and more popular.
