Electric Literature of 51516-70-2, These common heterocyclic compound, 51516-70-2, name is 5-Amino-1-(4-fluorophenyl)-1H-pyrazole-4-carbonitrile, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: Equimolar portionsof the intermediate compounds 1 (1 mmol) and the intermediatecompounds 3 (1 mmol) were dissolved in approximately 8 mL ofethanol. The reaction solution was allowed to stir at 80 8C for 2 huntil the reaction was complete. The reaction was monitored byTLC. Mostly, a precipitate formed and was then collected by suctionfiltration.
The synthetic route of 51516-70-2 has been constantly updated, and we look forward to future research findings.
