Reaction Steps

To a mixture of 3-benzyloxy-2-hydroxy-benzaldehyde (129, 1.0 g, 4.38 mmol) and cesium carbonate (2.14 g, 6.57 mmol) in N,N-dimethylformamide (50 mL), cyclopropylmethyl bromide (1.77 g, 13.1 mmol) was added at room temperature. The mixture was stirred at 40° C. for 3 days. The reaction mixture was poured into a solution of saturated ammonium chloride and was extracted with ethyl acetate. The organic layer was collected, washed with brine, and dried over magnesium sulfate. After removal of solvent, a viscous liquid was obtained (130, 1.21 g, 98%).
