Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 202865-83-6, name is 1-Bromo-3-fluoro-5-methylbenzene, This compound has unique chemical properties. The synthetic route is as follows., Recommanded Product: 1-Bromo-3-fluoro-5-methylbenzene
Example 148A 2-Bromo-6-fluoro-4-methylbenzaldehyde 1-Bromo-3-fluoro-5-methylbenzene (5.00 g, 26.5 mmol) was dissolved in tetrahydrofuran (100 mL) and cooled to -78 C. Lithium diisopropyl amide (1.8 M in tetrahydrofuran, 16.2 mL, 29.1 mmol) was added. After stirring at -78 C. for 30 min, N,N-dimethylformamide (2.32 g, 31.7 mmol) was added. After stirring at -78 C. for an additional 15 min, acetic acid (6 mL) and water (100 mL) was added and the mixture was warmed to RT. After extraction with ethyl acetate, the organic phase was washed with 1 M hydrochloride acid solution and brine, and dried over magnesium sulfate. Concentration in vacuo afforded the title compound (5.45 g, 95% of theory). GC-MS (Method 1G): Rt=4.39 min, MS (ESIPos): m/z=217 [M+H]+
