Reaction Steps
A 100 mL round-bottom flask was charged with 5-bromo-2-formylbenzoic acid (350 mg, 1.53 mmol, 1.00 equiv), N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (355 mg, 1.85 mmol, 1.20 equiv), 1-hydroxybenzotrizole (315 mg, 2.33 mmol, 1.50 equiv), dichloromethane (10 mL). The resulting solution was stirred for 15 min at room temperature. Dimethylamine (208 mg, 4.61 mmol, 3.00 equiv) was added. The resulting solution was stirred overnight at room temperature, diluted with water (20 mL), extracted with dichloromethane (3×20 mL) and the organic layers were combined, dried over Na2SO4, filtered and concentrated under reduced pressure. The residue was chromatographed on a silica gel column with ethyl acetate/petroleum ether (50/50) to provide 86.0 mg (22% yield) of 5-bromo-2-formyl-N,N-dimethylbenzamide as light yellow oil. LCMS (ESI, m/z): 256 [M+H]+.
