Synthetic Route of 1533519-84-4, New Advances in Chemical Research in 2021.Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, 1533519-84-4, name is 4-(4-Cyclopropylnaphthalen-1-yl)-1H-1,2,4-triazole-5(4H)-thione, molecular formula is C15H13N3S, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
In a 100 ml three-necked flask equipped with a stirrer and a thermometer, 25 ml of DMF was added, the intermediate (III)2.67 g, stirred at room temperature, 1.45 g of potassium carbonate was added, and 1.61 g of methyl bromoacetate was added dropwise at 25 C,Stirring was continued for 3 hours; 50 ml of water was added and extracted with ethyl acetate 50 ml x3 to combine the organic phase,The ethyl acetate was concentrated and concentrated, and 50 ml of methanol was added thereto. The crystals were recrystallized, filtered and dried to give 3.22 g of product,Namely intermediate (IV), yield 99.5%.
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 4-(4-Cyclopropylnaphthalen-1-yl)-1H-1,2,4-triazole-5(4H)-thione, hurry up and to see.
