Reference of 25016-11-9<\/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. 25016-11-9, name is 1-Methyl-1H-pyrazole-4-carbaldehyde, This compound has unique chemical properties. The synthetic route is as follows.<\/p>\n

Example 12: l-{l-[9-Methyl-8-(l-methyl-lH-pyrazol-4-yI)-9H-purin-6-yI]piperidin-4- yI}-l,3-dihydro-2H-benzimidazol-2-one (Compound 149)l H9-Methy -8-a-methyl-lH-pyrazol-^2H-benzimidazol-2-one[00207] To a solution of l-(l-(5-amino-6-(methylamino)pyrimidin-4-yl)piperidin-4-yl)- lH-benzo[d]imidazol-2(3H)-one (70 mg, 0.2 mmol) in anhydrous ethanol (8 mL) were added 1 -methyl- lH-pyrazole-4-carbaldehyde (34 mg, 0.3 mmol) and catalytic amount of hydrochloric acid (0.05 mL, 4M HCl in Dioxane, Aldrich). The reaction mixture was heated to 80 C for 18 hours. The resulting precipitate was collected by vacuum filtration, washed with ethanol (2 mL) and dried under reduced pressure, to give 62.6 mg (70% yield) of the title compound. NMR (400MHz, DMSO-d6): delta 10.84 (s, 1H), 8.41 (s, 1H), 8.25 (s, 1H), 8.02 (s, 1H), 7.13 (dd, 1H), 6.93 (m, 3H), 4.53 (m, 1H), 3.92 (s, 3H), 3.81 (d, 3H), 3.33 (m, 2H), 3.24 (m, 2H), 2.33 (m, 2H), 1.82 (d, 2H); MS (EI) for C22H23N9O: 430.4 (MH+).<\/p>\n

The chemical industry reduces the impact on the environment during synthesis 1-Methyl-1H-pyrazole-4-carbaldehyde. I believe this compound will play a more active role in future production and life.<\/p>\n
