Participants

Reaction Steps

To a solution of methyl 4-amino-3-hydroxybenzoate (2.5 g, 15.0 mmol) in dichloromethane (71 mL) and N,N-dimethylformamide (3.6 mL) was added N-bromosuccinamide (2.93 g, 16.5 mmol). The mixture was stirred at ambient temperature. After 15 min, the mixture was quenched with sat. sodium sulfite. Hydrochloric acid (1.0 M) was added and the mixture was extracted with dichloromethane (3×). The combined organic layer was washed with brine, dried over magnesium sulfate, filtered and concentrated. Purification by silica gel chromatography (100% hexanes→100% ethyl acetate) gave the title compound (1.2 g). LC-MS [M]=246.0.
