3-Hydroxybenzaldehyde (3 g, 24.6 mmol) and potassium carbonate (10.2 g, 73.8 mmol) were suspended in N,N-dimethylformamide (60 mL). Cyclopropyl methyl chloride (2.86 mL, 29.5 mmol) was added to this suspension, and stirred for 19 hours at room temperature. This mixture was partitioned into ethyl acetate and water. The organic layer was separated, washed with water, dried over anhydrous magnesium sulfate, and filtered. The filtrate was concentrated under a reduced pressure to obtain the title compound (4.32 g).
