Put in a three-necked bottle equipped with nitrogen protection device6-trifluoromethylindole (3.70g, 20mmol), 40ml of N,N-dimethylacetamide, stir and reduce the temperature to below 0,Add 60% sodium hydrogen (0.88g, 22mmol) in batches, keep warm and stir for 0.5 hours,Then add the filtrate of step one dropwise, after the addition, the temperature will rise naturally, and the reaction will be stirred overnight.Add 50ml water, extract three times with ethyl acetate (100ml×3), combine the organic phases,Wash with brine, dry with anhydrous sodium sulfate, and concentrate to dryness under reduced pressure.The concentrate is purified by silica gel chromatography,1-(3-Trichloro-pyridazin-4-yl)-6-trifluoromethyl-1H-indole (Intermediate 1-a) is obtained. |
