Related Products of 57012-20-1<\/a>, 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.<\/p>\n

Step 2: Preparation of 2,5-dimethyl-2H-pyrazole-3-carbaldehyde (15) A mixture of compound 14 (3 grams, 23.8 mmol) and pyridinium dichromate (13.4 grams, 35.7 mmol) in dichloromethane (100 mL) was stirred at 25 C. under nitrogen atmosphere for 16 hours. The reaction mixture was then filtered. The filtrate was collected, dried over anhydrous Na2SO4 and concentrated under reduced pressure. The crude thus obtained was passed through the silica gel to afford the desired compound 2,5-dimethyl-2H-pyrazole-3-carbaldehyde (15) 1 gram as a brown solid. Yield: 34%; 1H NMR (200 MHz, CDCl3): delta 9.8 (s, H), 6.6(s, H), 4.1 (s, 3H), 2.3 (s, 3H). Mass (CI method, i-butane): 125 (M+1, 100%); IR: numax (KBr, cm-1): 1688.<\/p>\n
