Potassium Carbonate → 5-Chloro-2-(2,2,2-trifluoroethoxy)benzaldehyde

참여 물질

반응 단계

5-Chloro-2-hydroxy-benzaldehyde (3.1 g, 2 mmol), 1,1,1-trifluoro-2-iodo-ethane (2.4 mL, 24 mmol), K2CO3 (5.5 g, 40 mmol) and KI (0.1 g) were mixed in DMF (20 mL). Then the mixture was irradiated under microwave at 180° C. for 1 h. The mixture was filtered and the filtrate was concentrated. The residue was dissolved in ethyl acetate and washed with 1N NaOH. Then the organic layer was separated, dried over anhydrous Na2SO4 and concentrated to give title compound as a yellow solid (Yield: 4 g).
