Synthesis

626-41-5

68-12-2

199177-26-9

Step-1: Synthesis of 3-bromo-5-hydroxybenzaldehyde: 2.5 M n-butyllithium (n-BuLi, 7.9 mL, 19.84 mmol) was slowly added dropwise to a solution of 3,5-dibromophenol (2.5 g, 9.92 mmol) in tetrahydrofuran (THF, 25 mL) at -78°C for a controlled time of 15 min. The reaction mixture was continued to be stirred at -78 °C for 20 min, followed by dropwise addition of dry N,N-dimethylformamide (DMF, 15.29 mL, 198.4 mmol). After maintaining the reaction at -78 °C for 30 min, the reaction mixture was warmed up to room temperature and stirred for 1 hour. Upon completion of the reaction, the reaction was quenched with saturated ammonium chloride solution (200 mL) and extracted with ethyl acetate (EtOAc, 3 x 250 mL). The organic layers were combined, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The crude product was purified by silica gel column chromatography (100-200 mesh, eluent: 0-6% hexane solution of ethyl acetate) to afford the target compound 3-bromo-5-hydroxybenzaldehyde (1.0 g, 50.12% yield) as a white solid. Nuclear magnetic resonance hydrogen spectrum (1H NMR, 400 MHz, DMSO-d6): δ (ppm): 10.5 (broad peak, 1H), 9.85 (single peak, 1H), 7.50 (single peak, 1H), 7.25 (double peak, 2H).
