As a common heterocyclic compound, it belong phthalazine compound,Phthalazin-1(2H)-one,119-39-1,Molecular formula: C8H6N2O,mainly used in chemical industry, its synthesis route is as follows.,119-39-1
Weigh 0.324g of commercial compound C1a dissolved in 3ml DMF,60% NaH 0.16g was added under ice bath.Stir for 30 minutes and add 0.591 g of ethyl 4-(bromomethyl)benzoate.Stir for 1 hour at room temperature. Pour the reaction mixture into 100ml of crushed ice.Extract several times with ethyl acetate, combine the organic layers, and evaporate.Light yellow solid (Intermediate C1b).Dissolve this intermediate in 10 ml of THF and add 2.9 ml of 8N NaOH.Return overnight. The reaction solution was diluted with water, and the aqueous layer was washed with ethyl acetate.The aqueous layer was adjusted to pH 6 with 6N HCl, precipitated and filtered.The precipitate is washed with water and dried to give a beige product C1c
With the synthetic route has been constantly updated, we look forward to future research findings about Phthalazin-1(2H)-one,belong phthalazine compound
