2-Bromo-4-cyanobenzaldehyde Use and Manufacturing
A solution of the product of Part 3A (8.80 g, 24.9 mmol) was dissolved in wet DMSO (83 mL) at ambient temperature then warmed to 120 °C and maintained 6 h. After cooling to ambient temperature, the resulting solution was diluted with H3-Bromo-4-formyl-benzonitrile (intermediate 2, 3.25 g, 14.7 mmol) is stirred with acetylacetone (2.42 mL, 19.1 mmol), 3-(trifluoromethyl)phenylurea (3 g, 14.7 mmol) and polyphosphoric acid (3.02 g, 7.90 mmol) in tetrahydrofurane (80.0 mL) at 60 °C for 48 h. The reaction mixture is concentrated in vacuo and ethyl acetate and water is added and the phases are separated. The aqueous phase is extracted twice with ethyl acetate. The combined organic phases are washed with saturated sodium chloride solution, dried over MgS04 and concentrated. Yield: 7.66 g; ESI mass spectrum: [M+ H]+ = 508; Retention time HPLC: 1.14 min (HPLC method Z018 S04)
