Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 19959-77-4, name is 2-(5-Methyl-1H-pyrazol-3-yl)pyridine, This compound has unique chemical properties. The synthetic route is as follows., name: 2-(5-Methyl-1H-pyrazol-3-yl)pyridine
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%), M. p. >300C. Anal. Calc. for C9H9Cl2N3Zn (FW, 295.46): C, 36.58; H, 3.07; N, 14.22. Found: C, 36.08; H, 3.53; N, 13.79%. Selected IR data (KBr, cm-1): 3175(s), 3133 (s), 3109 (m), 3087 (m), 2924 (s), 2853 (s), 1611 (m) (nu(C=N)), 1573 (m) (delta(C=C)), 1446 (s) (nu(CH3)), 1303 (m) (nu(C-N)), 1261 (w), 1114 (w), 1053 (w), 1023(w), 988 (s), 823 (m), 793 (s), 738 (m).
