As a common heterocyclic compound, it belongs to phthalazine compound, name is 1,4-Dioxo-1,2,3,4-tetrahydrophthalazine-6-carboxylic acid, and cas is 42972-13-4, its synthesis route is as follows.,42972-13-4
Bromo-4-oxo-3,4-dihydro–phthalazine-6-carboxylic acid: 1,4-Dioxo-1,2,3,4-tetrahydrophthalazine-6-carboxylic acid (91.0 g, 0.44 mol) was suspended in DCE (1.0 L) and phosphorus pentabromide (761.0 g, 1.77 mol) was added in three portions and the reaction heated to reflux for 24 hours. The reaction was cooled to RT and poured onto ice (2.50 kg) and the resulting precipitate filtered and washed with water to give the crude product (130 g).
With the complex challenges of chemical substances, we look forward to future research findings about 42972-13-4,belong phthalazine compound
