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., Computed Properties of C9H9N3
A 5mL methanol solution of L (0.2mmol, 31.8mg) and m-phthalic acid (0.2mmol, 33.2mg) was mixed with a 5mL methanol solution of Mn(HCOO)2·2H2O (0.1mmol, 14.5mg), and the resulting mixture was then stirred 15min to obtain a colorless solution. This colorless solution was filtered and left to evaporate for one week, giving rise to colorless stick-like crystals. The resulting crystals were washed with n-hexane 2?3 times, then dried in vacuum. Yield: 47.1mg (67%), M. p. > 300C. Anal. Calc. for C34H28MnN6O8 (FW, 703.56): C, 58.04; H, 4.01; N, 11.95. Found: C, 58.98; H, 4.73; N, 11.49%. Selected IR data (cm-1, KBr): 3256 (b, s), 3128 (m), 3073 (m), 2925 (m), 2883 (m), 1694 (s) (nu(C=O)), 1606 (m) (nu(C=N)), 1561 (s) (nu(C=C)), 1428 (m) (delta(CH3)), 1392 (s), 1296 (m) (nu(C-N)), 1161 (w), 777 (m), 733 (m), 689 (m).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
