Versuchsvorschrift

To a solution of 4-[6-(2-benzyloxycarbonylaminoethyloxy)-3-cyanoindol-1-yl]-2-methoxymethoxybenzoic acid ethyl ester (0.14 g) in a mixed solvent of ethanol (2.5 mL), tetrahydrofuran (5 mL), and water (2.5 mL) was added lithium hydroxide mono hydrate (0.03 g), and this mixture was stirred at room temperature for 3 hours. To this reaction mixture was added 2 mol/L hydrochloric acid (0.75 mL), and this mixture was stirred at 50° C. for 5 hours. This reaction mixture was treated 1 mol/L hydrochloric acid (5 mL), and this mixture was concentrated under reduced pressure until this solvent volume became one-third. The precipitated solid was collected by filtration, and washed with water, methanol and ether to give the title compound (0.097 g)
