Versuchsvorschrift

A solution of 3-(4-benzoylamino-phenylmethyl)-1-methyl-1H-indole-5-carboxylic acid methyl ester (69 mg, 0.17 mmol), sodium hydroxide (21 mg, 0.52 mmol), methanol (3 mL), water (1 mL) and THF (3 mL) was heated to 60° C. for 24 hr. The reaction solution was then cooled to room temperature and concentrated in vacuo. The remaining residue was diluted with ethyl acetate (20 mL) and washed with 1N HCl (20 mL). The organic layer was dried over MgSO4, filtered and concentrated to provide 3-(4-benzoylamino-phenylmethyl)-1-methyl-1H-indole-5-carboxylic acid (64 mg, 98% yield).
