11 g of 3-(p-hydroxybenzoyl)indole and 7.43 g of sodium hydroxide were dissolved in 10 ml of water. 20.51 g of 3-chloro-1,2-propandiol was added to the solution followed by reflux with stirring for 3 hours in oil bath. After cooling, the solution was evaporated to dryness. The residue was purified by column chromatography on silica gel. After recrystallization from ethyl acetate, 3-[p-(2,3-dihydroxypropoxy)benzoyl]indole (compound 16) was obtained in the form of white crystals. (Yield: 13.8%).
