Reaction Steps

Trimethylsilyldiazomethane (2 M solution in diethyl ether, 0.409 mL, 0.818 mmol) was added to a solution of (3-bromo-4-hydroxy-5-methoxy-phenyl)-acetic acid (150 mg, 0.575 mmol) in methanol (1 mL) and toluene (4 mL), and the mixture was stirred at room temperature for 30 minutes. Acetic acid was added to the reaction mixture to terminate the reaction, and then the mixture was concentrated under reduced pressure to give the target compound as a colorless oil (158 mg, 99%).
