Electric Literature of 4922-98-9, New discoveries in chemical research and development in 2021. We’ll be discussing some of the latest developments in chemical about CAS: 4922-98-9, name is 5-Phenyl-1H-1,2,4-triazol-3-amine, 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: Initially, amidoguanidines (7) were prepared via the reaction of substituted benzoyl chloride (5) (10 mmol) and aminoguanidine hydrochloride (6) (20 mmol). The obtained intermediates (7) were then treated with microwave irradiation power (100 W) for 8-15 min in water to generate 5-amino-1,2,4-triazoles (8) [18] . Subsequently, 5-amino-1,2,4-triazoles (8) (3 mmol) were reacted with ethoxycarbonyl isothiocyanate (3.3 mmol) in anhydrous DMF (4 ml) at room temperature, leading to formation of thiourea derivatives (9).
The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.Read on for other articles about 5-Phenyl-1H-1,2,4-triazol-3-amine, hurry up and to see.
