Water → methyl trans-3-[3-(4-fluorophenyl)-1-isopropyl-1H-indol-2-yl]acrylate

Participants

Reaction Steps

0.62 g of 3-(4-fluorophenyl)-1-isopropyl-1H-indole, 0.57 g of methyl trans-3-methoxyacrylate, 46 mg of water and 6.4 mL of glacial acetic acid were mixed, then, 66 mg of phosphorus oxychloride was added dropwise into the mixture at an inner temperature of 25° C., the added mixture was stirred for 21 hours at the same temperature to cause a reaction. After completion of the reaction, the same post treatment was conducted as in Example 1 to obtain 0.65 g of methyl trans-3-[3-(4-fluorophenyl)-1-isopropyl-1H-indol-2-yl]acrylate (yellow solid). Yield: 79%.
