4-hydroxy-3-methoxy-benzoic acid methyl ester (1.0 g, 5.5 mmol, 1.0 eq) was dissolved in acetone (14 mL), NaI (0.5 eq) and K2CO3 (1.0 g, 2.0 eq) were added and the mixture was stirred at room temperature for 30 min. (Bromomethyl)cyclopropane (0.53 mL, 0.9 eq) was added, and the mixture was refluxed for 2 days. The solvent was concentrated under reduced pressure, NaOH 10% was added, and it was extracted with DCM and dried. The title product (1.21 g, yield 93%) was recovered and used without further purification.
