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. 19959-77-4, name is 2-(5-Methyl-1H-pyrazol-3-yl)pyridine, A new synthetic method of this compound is introduced below., Formula: C9H9N3
General procedure: A 5mL ethanol solution of L (0.2mmol, 15.9mg) and Et3N (0.1mmol, 14mul) was mixed with a 5mL ethanol solution of ZnCl2 (0.1mmol, 13.6mg), and the resulting mixture was then stirred for 15min to obtain a colorless solution. This colorless solution was filtered and left to evaporate for three days, giving rise to colorless rod-like crystals. The resulting crystals were washed with n-hexane 2?3 times, then dried in vacuum. Yield: 23.6mg (80%),
The synthetic route of 19959-77-4 has been constantly updated, and we look forward to future research findings.
