N-bromobutanimide → HCID 23157338, compound

Participants

Reaction Steps

To a solution of methyl 3-isopropoxy-4-methylbenzoate (1.0 g, 4.8 mmol) in ethyl acetate (20 mL) were added N-bromosuccinimide (0.92 g, 5.19 mmol) and 2,2′-azobis(isobutyronitrile) (3 mg), and the mixture was heated under reflux for 6 hr. The reaction mixture was cooled, washed with water and saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=10/1-hexane/ethyl acetate=4/1) to give the title compound (0.89 g, yield 64%) as a colorless oil. MS (ESI+): 287 (M+H), 289.
