Reaction Steps

To a solution of 5-benzyloxy-6-methyl-1H-indole-2-carboxylic acid methyl ester (1.3 g) in a mixed solvent of 1,4-dioxane (40 mL) and water (20 mL) was added Lithium hydroxide mono hydrate (1.8 g) at room temperature and this mixture was stirred at 50° C. for 1 hour. After this reaction mixture was cooled to room temperature, 1 mol/L hydrochloric acid was added. This precipitated solid was collected by filtration, and washed with water, dried under reduced pressure to give the title compound (1.0 g).
