1-(5-Bromo-2,4-difluoro-phenyl)-ethanone Use and Manufacturing

Preparation of intermediate 19: l-(5-bromo-2, 4-difluoro-phenyl)-ethanoneA mixture of A1C1Intermediate 18 (1-18)difluorophenyl)ethanoneA mixture of A1C11-(5-Bromo-2, 4-difluorophenyl)ethanone To a solution of 1, 5-dibromo-2, 4-difluorobenzene (Nucleosides, Nucleotides nucleic Acid, 201 (1 and2), 11-40 (2001) ) (8.8 g, 32.4 mmol) in diethylether (60 ml), 1.6 M n-BuLi in hexane (24.3 ml, 1.2 eq) was added at-78 C under N2 atmosphere. After stirring the reaction mixture at-78 C for 30 min, N-methyl-N- (methyloxy) acetamide (5.0 g, 1.5 eq) was dropped into to quench the reaction. The reaction mixture was stirred at the same temperature for further 30 min. After added acetic acid ( (5.2 ml), water (78 ml), the reaction mixture was extracted with diethylether. The obtained organic phase was washed by 0.2 N HCI aqueous, water, saturated NaHC03 aqueous and saturated NaCI aqueous, and dried over MgS04. After removing the solvent under reduced pressure, the residue was purified by Silica gel chromatography (n-Hexane/EtOAc = 49/1). Desired compound was obtained as pale yellow oil (4.94 g, 65percent).
