Participants

Reaction Conditions

Reaction Steps

A mixture of methyl 4-acetyl-2-fluorobenzoate (1.6 g, 8.2 mmol) and 8.8M hydrogen bromide in water (2.8 mL) in dimethyl sulfoxide (20 mL) was stirred at 60° C. overnight. After cooling, the mixture was poured into ice-water. The reaction mixture was extracted with diethyl ether. The combined organic extracts were washed with brine, dried over sodium sulfate, filtered and concentrated to yield the desired product which was used in the next reaction step without further purification. (1.60 g, 93.3%).
