Reaction Steps

To a solution of 3 g 1-(4-Methoxy-phenyl)-1H-indole-2-carboxylic acid methyl ester in 50 ml THF, 10 ml water and 0.58 g lithium hydroxide monohydrate were added. After stirring for 2 h at 60° C. the reaction was cooled to RT. The mixture was acidified with half concentrated hydrochloric acid and the precipitate was collected by filtration and was washed with 10 ml water The product was obtained as a white solid which was dried under reduced pressure. Yield: 520 mg.
