4-Bromo-2-fluoro-N-methylbenzamide Chemical Properties,Usage,Production

Uses

4-Bromo-2-fluoro-N-methylbenzamide is an intermediate in the synthesis of MDV 3100 (M199800), is an androgen-receptor antagonist that blocks androgens from binding to the androgen receptor and prevents nuclear translocation and co-activator recruitment of the ligand-receptor complex.

Synthesis

112704-79-7

74-89-5

749927-69-3

Step 1: Synthesis of 4-bromo-2-fluoro-N-methylbenzamide To a 100 mL round-bottomed flask were added 4-bromo-2-fluorobenzoic acid (3.0 g, 13.7 mmol), 2 M aqueous methylamine (34.3 mL, 68.5 mmol), 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDCI, 6.6 g, 34.25 mmol), 1-hydroxybenzotriazole (HOBt, 2.8 g 20.6 mmol), N,N-diisopropylethylamine (DIPEA, appropriate amount) and N,N-dimethylformamide (DMF, 50 mL). The reaction mixture was stirred at room temperature for 16 hours. Upon completion of the reaction, the reaction was quenched by the addition of water (50 mL). The aqueous phase was separated and the organic phase was extracted with ethyl acetate (3 x 50 mL). The organic phases were combined, dried with anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The crude product was purified by silica gel column chromatography with the eluent ethyl acetate/petroleum ether (1:3, v/v) to afford the title compound 4-bromo-2-fluoro-N-methylbenzamide as a white solid (2.34 g, 74% yield). Mass spectrum (MS): [M+H]+ 232.
