In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 6579-54-0 as follows. 6579-54-0

(a) Step 1 [0256] A solution of 1H-indole-3-carboxaldehyde (0.290 g, 2.00 mmol) in methylene chloride (4 mL) was added with 2,6-dichlorophenylsulfonyl chloride (0.589 g, 2.40 mmol) and diisopropylethylamine (0.310 g, 2.40 mmol), and the mixture was stirred overnight at room temperature. The reaction mixture was added with saturated aqueous sodium hydrogencarbonate to terminate the reaction, and then extracted three times with methylene chloride. The organic layer was dried over anhydrous magnesium sulfate, then the solvent was evaporated, and the resulting residue was purified by silica gel column chromatography (hexane/ethyl acetate) to obtain 1-(2,6-dichlorophenylsulfonyl)-1H-indole-3-carboxaldehyde (0.658 g, 93%).1H NMR (300 MHz, CDCl3) delta 7.32-7.38 (m, 2H), 7.41-7.45 (m, 1H), 7.48-7.51 (m, 2H), 7.63-7.67 (m, 1H), 8.28-8.31 (m, 1H), 8.41 (s, 1H), 10.18 (s, 1H).
