Participants

Reaction Steps

This product is prepared by refluxing for 3 hours a solution of 10 g (34.81 mmol) of 5-fluoro-1-[(3-fluorophenyl)methyl]-1H-indole-2-carboxylic acid, prepared in step 1.1, and 25.4 mL (0.348 mol) of sulfonyl chloride in 174 mL of toluene. After this time, the reaction mixture is concentrated under reduced pressure. The resulting mixture is taken up twice successively in 100 mL of toluene and then concentrated under reduced pressure. The product is used in the rest of the synthesis without a further purification step.
