119-39-1, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. Phthalazin-1(2H)-one, cas is 119-39-1,the phthalazine compound, it is a common compound, a new synthetic route is introduced below.
Weighing 2H-phthalazin-1-one (150 mmol), tert-butyl 5-{[(2-chlorophenoxy)carbonyl]amino}-3,4-dihydroisoquinoline-2(1H)-carboxylate (195 mmol) in reaction bottle, adding DMF100ml, 55 C lower reaction overnight, stopping the reaction, by adding water 100 ml, dichloromethane 200 ml, extraction, separation of the organic phase, the aqueous phase to continue to dichloromethane is used for extraction (3 * 50 ml), the combined organic phase, anhydrous sodium sulfate drying, column chromatography purification obtained title compound.
The chemical industry reduces the impact on the environment during synthesis,119-39-1,Phthalazin-1(2H)-one,I believe this compound will play a more active role in future production and life.
