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. 57012-20-1, name is (1,3-Dimethyl-1H-pyrazol-5-yl)methanol, This compound has unique chemical properties. The synthetic route is as follows., Formula: C6H10N2O
Example 1.2: Preparation of 2,5-dimethyl-2H-pyrazole-3-carbaldehyde1.3 g of oxalic acid chloride in 40 ml DCM were cooled to -700C and 1 ,6 g DMSO in 10 ml DCM were added dropwise. After 5 min of stirring at -700C 1 g of (2,5-dimethyl- 2H-pyrazol-3-yl)-methanol (example 1.1 ) in 10 ml DCM and 6 g triethylamine were added and the reaction mixture was allowed to warm to about 20 to 25C. After extrac- tion with water the reaction mixture was dried. After removing the solvents in vacuo, the resulting residue was purified by column chromatography over silica with cyclohex- ane/ethylacetate mixtures yielding 0.6 g of the title compound as a yellowish oil. 1H-NMR (CDCI3, delta in ppm): 9.8 (s, 1 H); 6.7 (s, 1 H); 4.1 (s, 3H); 2.3 (s, 3H).
