Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 24517-64-4, name is 2-Amino-3-cyanopyridine. A new synthetic method of this compound is introduced below., Recommanded Product: 2-Amino-3-cyanopyridine
Synthesis of imidazo [1 ,2-a]pyridine- 8-carbonitrile. To a solution of 2-aminonicotinonitrile (1.0 g, 8.39 mmol) in EtOH (10 ml) in a 20m1 sealed vialwas added 2-chloroacetaldehyde (1.611 ml, 9.23 mmol) vial was then sealed and heated to 120C overnight. Reaction was cooled to RT and quenched with 2N Na2CO3, removed EtOH invaccuo and extracted with DCMx3. Combined organics and washed with water then brinex2.Dired over sodium sulfate and removed solvent to give title compound as a yellow brown solid(1.2 g, 8.38 mmol, 100 % yield) was verified by MS (ES+) C8H5N3 requires: 143 found: 144 [M+H]
