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. 51516-67-7, name is 5-Amino-1-(4-chlorophenyl)-1H-pyrazole-4-carbonitrile, This compound has unique chemical properties. The synthetic route is as follows., Computed Properties of C10H7ClN4
General procedure: In a round bottomed flask of 100 mL equipped with a condenser we added a solution of 2-substituted-3-aminopyrrole-4-carbonitrile 4 (1 mmol) with either cyclopentanone or cyclohexanone (1.4 mmol) in 30 mL of distilled 1,2-dichloroethane.Anhydrous AlCl3 (4 mmol) was then added, and the mixturewas refluxed for 30 and 32 min, respectively, under microwaveirradiation (at a constant power of 400 W). The mixture wasthen cooled to room temperature. After cooling a mixture oftetrahydrofurane and water (1 : 1, 20 mL) was added, followedby the drop wise addition of NaOH (aq. solution 10%) untilthe solution was basic. After this, the mixture was stirred for30 min, and extracted with dichloromethane (3×20 mL). Thecombined extracts were washed with saline (20 mL), driedover MgSO4, filtered, and the solvent evaporated to obtain asolid, which was identical in all respects with that obtainedfrom the thermal method (mp, TLC, NMR).
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 51516-67-7.
