180 °C

A mixture of 3-bromo-5-ethoxy-4-(methoxymethoxy)benzaldehyde (600 mg, 2.1 mmol) and CuCN (280 mg, 3.1 mmol) in DMF (10 mL) was heated at 180° C. for 4 hours. TLC (PE:EtOAc=1:1) indicated that the most of the starting material was consumed. The solvent was removed in vacuo, and the residue was purified by column chromatograph to afford 3-ethoxy-5-formyl-2-hydroxybenzonitrile (200 mg, yield: 50.0%).
