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. 1120-82-7, name is (1H-Pyrazol-1-yl)methanol, A new synthetic method of this compound is introduced below., Recommanded Product: 1120-82-7
Cystamine dihydrochloride (1.90 g, 8.43 mmol), N-hydroxymethylpyrazole(3.32 g, 33.9 mmol) and triethylamine (1.76 g,17.5 mmol) dissolved in dichloromethane (50 mL) were stirredfor 24 h at RT. The reaction mixture was extracted with water(30 mL) three times, after which the organic layer was dried overMgSO4 and the solvent was evaporated. This yielded L3 as a colorlessoil (3.96 g, 8.38 mmol, 99%), which was used without furtherpurification. 1H NMR (300 MHz, CD3CN, RT): d 2.65 (t, J = 7 Hz,4H, S-CH2), 2.94 (t, J = 7 Hz, 4H, S-CH2-CH2), 5.07 (s, 8H, N-CH2-Pz), 6.27 (t, J = 2 Hz, 4H, N-CH-CH), 7.47 (d, J = 1 Hz, 4H, N-CH),7.63 (d, J = 2 Hz, N-CH). 13C NMR (75 MHz, CD3CN, RT): d 37.1 (SCH2),50.2 (S-CH2-CH2), 68.9 (N-CH2-Pz), 106.6 (N-CH-CH), 130.8(N-CH), 140.1 (N-CH). ESI-MS found (calculated) for [M+Na]+ m/z495.0 (495.2); [MC3+Na]+ m/z 459.0 (459.2); [M2 C3+Na]+ m/z422.9 (423.2); [M3 C3+Na]+ m/z 387.0 (387.2); [M4 C3+Na]+m/z 350.9 (351.2).
