Reaction Steps

The mixture of 4.80 g of 3-(trifluoroacetyl)-1H-indole, 1.35 g of paraformaldehyde and 0.10 g of triethylamine was stirred at 130° C. for 2 hours. After the reaction mixture was cooled to room temperature, acetone was added to the reaction mixture. The mixture was filtered, and then the filtrate was concentrated under reduced pressure. The residue was subjected to silica gel column chromatography, and hexane was added to the residue, as a result, a crystal was formed. The crystal was collected to obtain 5.36 g of 3-(trifluoroacetyl)-1H-indole-1-ylmethanol.
