2-Fluoro-5-((4-oxo-3,4-dihydrophthalazin-1-yl)methyl)benzonitrile, cas is 1021298-68-9, it is a common heterocyclic compound, the phthalazine compound, its synthesis route is as follows.,1021298-68-9
(c) 2-Fluoro-5-[(4-oxo-3,4-dihydrophthalazin-1-yl)methyl]benzoic acid (D) 2-Fluoro-5-[(4-oxo-3,4-dihydrophthalazin-1-yl)methyl]benzonitrile (ED) (9.60 g, 34.37 mmol) and water (40 ml) were stirred at 200C. 2M Sodium hydroxide (36 ml, 72.00 mmol) was added, the reaction mixture warmed to 9O0C and held at this temperature overnight. The reaction mixture was cooled to room temperature and filtered. The filter pad was washed with water (10 ml) and the combined filtrate added to 2M HCI (56 ml, 112.00 mmol) at 600C over 40 minutes. The resulting suspension was cooled to 50C and filtered, washed with water (57 ml) and dried in vacuo at up to 6O0C to give the title compound as a white solid (9.72 g).Mass Spectrum: MH+ 2991 H NMR (400MHz. DMSO-d6) delta: 4.36 (s, 2H), 7.24 (dd, 1 H), 7.59 (m, 1 H), 7.84 (dt, 2H), 7.90(dt, 1 H), 7.98 (d, 1 H), 8.27 (dd, 1 H), 12.59 (s, 1 H), 13.22 (br s, 1 H).
With the rapid development of chemical substances, we look forward to future research findings about 2-Fluoro-5-((4-oxo-3,4-dihydrophthalazin-1-yl)methyl)benzonitrile
