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. 4928-87-4, name is 1,2,4-Triazole-3-carboxylic acid, This compound has unique chemical properties. The synthetic route is as follows., SDS of cas: 4928-87-4
A mixture of l-(7-Amino-5-(-8-azabicyclo[3.2.1]octan-3-yl)-3-(6-phenylpyridin-3- yl)pyrazolo[l,5-a]pyrimidin-6-yl)ethanone (131.4mg, 0.30 mmol), N2H4.H2O (150 ul, 3.0 mmol) in NMP (10 ml) was heated first at 100C for 30 min and then at 200C for 60 min under microwave condition. The mixture was put on rotovap and concentrated at 60C for 2h to remove excess N2H4.H20. lH-l,2,4-triazole-3-carboxylic acid (101.7 mg, 0.90 mmol), EDC (229 mg, 1.20 mmol), HOBt (121.5 mg, 0.90 mmol) and DIEA (521.6 uL, 3.0 mmol) were then added and the mixture was stirred at room temperature for lh. Purification with prep-LC pro ided (( 1 R,3 s,5 S)-3 -(3 -methyl-6-(6-phenylpyridin-3 -yl)- 1 H-dipyrazolo [1,5- a:4′,3′-e]pyrimidin-4-yl)-8-azabicyclo[3.2.1]octan-8-yl)(4H-l,2,4-triazol-3-yl)methanone.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 4928-87-4.
