Synthesis
5-(2-Fluorophenyl)-1-(pyridin-3-ylsulfonyl)-1H-pyrrole-3-carbaldehyde is prepared by the reaction of 3-pyridinesulfonyl Chloride and 5-(2-fluorophenyl)-1H-pyrrole-3-carbaldehyde. The specific synthesis steps are as follows:
Take 10.0g (52.86mmol) of compound, 5.9g (58.15mmol) of triethylamine and 100mL of dichloromethane, cool the system to 0°C, add dropwise a dichloromethane solution (100mL) of compound G (58.15mmol), and add dropwise After completion, the system was reacted at room temperature for 6 hours, 100mL of water was added and washed twice, the organic phase was dried with anhydrous sodium sulfate, and concentrated under reduced pressure to obtain 16.4g of 5-(2-Fluorophenyl)-1-(pyridin-3-ylsulfonyl)-1H-pyrrole-3-carbaldehyde, with a yield of 93.8%.
