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. 116557-46-1, name is 3-Bromo-2-methoxyaniline, This compound has unique chemical properties. The synthetic route is as follows., HPLC of Formula: C7H8BrNO

Step 3[00174j IntlO (2.0 g, 9.9 mmol) was dissolved in dioxane (40 mL) and the vessel purged with nitrogen for 5 minutes. Next bis(pinacolato)diborone (3.77 g, 14.85 mmol), [1,1 ?-bis(diphenylphosphino)ferrocene] dichloropalladium (II) complex with dichloromethane (404 mg, 0.49 mmol) and potassium acetate (2.91 g, 29.7 mmol) were added. The flask was evacuated and backfilled with nitrogen, and then heated to 100 Cfor 15 hours. Water was added to quench the reaction and the product was then extracted with EtOAc. The combined organic layers were washed with brine (x3), dried over sodium sulfate, filtered, concentrated and purified using automated chromatography (elutes at 40% ethyl acetate) to provide Intl 1 (2.0 g, 8 1%). ?H NMR (400MHz, chloroform-d) oe 7.12 (dd,J=7.3, 1.8 Hz, 1H), 6.96-6.89 (m, 1H), 6.88-6.83 (m, 1H),3.82 (s, 3H), 1.37 (s, 12H). LC retention time 0.65 [J]. m/z: 250 (MHj.
