With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.119-39-1,Phthalazin-1(2H)-one,as a common compound, the synthetic route is as follows.
Weigh 2H-phthalazin-1-one (150 mmol),(3,4-Dihydroisoquinoline-2(1H)-carboxylic acid tert-butyl ester-5-yl)-aminoO-chlorobenzyl formate (195 mmol) in a reaction flask,Add DMF100ml,The reaction was carried out at 55 C overnight.Stop the reaction,Add 100ml of water,200ml of dichloromethane,extraction,Separating the organic phase,The aqueous phase was further extracted with dichloromethane (3*50 ml).Combine the organic phase,Dry over anhydrous sodium sulfate,Purification by column chromatography gave the title compound., 119-39-1
The synthetic route of 119-39-1 has been constantly updated, and we look forward to future research findings.
