実験手順
Methyl 5-cyano-2-hydroxybenzoate (Astatech, 3.0 g, 16.9 mmol), 1-bromo-2-methoxyethane (2.6 g, 18.6 mmol), and K2CO3 (2.3 g, 16.9 mmol) were mixed in 25 mL of DMF and heated at 60° C. for 48 hours. The reaction was diluted with 100 mL of EtOAc washed with water, brine, dried with MgSO4 and the solvent removed to provide the title compound. 1H NMR (300 MHz, CHLOROFORM-D) δ ppm 3.46 (s, 3H) 3.79-3.84 (m, 2H) 3.90 (s, 3H) 4.23-4.28 (m, 2H) 7.07 (d, J=8.82 Hz, 1H) 7.72 (dd, J=8.65, 2.20 Hz, 1H) 8.11 (d, J=2.37 Hz, 1H). MS (DCI/NH3) m/z 236.0 (M+H)+.
