Reaktionsschritte

A solution of trimethylsilyldiazomethane in hexane (2 M, 1.4 mL, 2.8 mmol) was added to a solution of 4-bromo-phenyl-hydroxy-acetic acid (506 mg, 2.19 mmol) in benzene (2.1 mL)-methanol (1.0 mL) under cooling with ice, and the mixture was stirred at room temperature for five minutes. The reaction mixture was concentrated under reduced pressure. The residue was purified by silica gel chromatography (hexane/ethyl acetate=3/1) to give the title compound (500 mg, 93%).
