반응 단계
Dissolve 2-chloro-4-hydroxy-benzaldehyde (1.09 g, 7.01 mmol) in DMF (10 mL), add K2CO3 (1.06 g, 7.7 mmol) and 4-fluorobenzonitrile (932 mg, 7.7 mmol), heat the mixture at 130° C. overnight. Add water and extract the aqueous layer with EtOAc. Combine organic layers and dry over Na2SO4. Eliminate the solvent and purify by flash chromatography on silica gel (eluent: EtOAc/hexane 15/85) to give the title compound (240 mg, 14%), 1H-NMR (CDCl3, 300 MHz): 10.40 (s, 1H), 7.98 (d, 1H, J=8.6 Hz), 7.74-7.71 (m, 2H), 7.17-7.00 (m, 4H).
