According to the analysis of related databases, 67832-11-5, the application of this compound in the production field has become more and more popular.

In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 67832-11-5 as follows. HPLC of Formula: C8H6BrN

Compound BB-2H-1 (11.50 g, 58.66 mmol) was dissolved in carbon tetrachloride (150 mL) at room temperature, followed by addition of N-bromobutanimide (31.32 g, 175.98 mmol) and benzoyl peroxide (1.42 g, 5.87 mmol). After completion of the addition, the reaction mixture was heated to 85 C and stirred for 10 hours. After completion of the reaction, the mixture was cooled to room temperature, followed by filtration. The filter cake was wash with ethyl acetate (50 mL). The filtrate was combined and concentrated under reduced pressure. The obtained residue was dissolved in ethyl acetate (50 mL), washed with saturated brine (100 mL×2), dried over anhydrous sodium sulfate, filtered to remove the desiccant, and concentrated under reduced pressure to obtain the title compound BB-2H-2 (pale-yellow solid, 20.00 g). The crude product was used directly in the next step without purification. 1H NMR (400MHz,CDCl3) delta: 8.18 (d, J = 1.8 Hz, 1H), 7.60 (dd, J = 1.8, 8.3 Hz, 1H), 7.48 (d, J = 8.3 Hz, 1H), 6.92 (s, 1H).

According to the analysis of related databases, 67832-11-5, the application of this compound in the production field has become more and more popular.
