Versuchsvorschrift

To a mixture of p-cresol (500 mg, 4.63 mmol) and ethyl 2-bromoacetate (928 mg, 5.56 mmol) in CH3CN (10 mL) was added K2CO3 (3 g, 21.7 mmol). The reaction mixture was stirred at 80° C. for 4 h. The solid was removed by filtration and the filtrate was concentrated to give the title compound which was used in the next step without further purification.
