Versuchsvorschrift

A solution of 4-(cyclopropylmethoxy)benzoic acid (576 mg), ethyl 5-amino-1H-indole-2-carboxylate (612 mg), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (690 mg), 1-hydroxybenzotriazole (551 mg) and N,N-dimethylaminopyridine (367 mg) in DMF (20 mL) was stirred at room temperature for 2 hr. The reaction solution was extracted with ethyl acetate, washed with aqueous sodium hydrogen carbonate solution and saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue (brown solid) was washed with a small amount of ethyl acetate to give the title compound (820 mg, yield 72%).
