Versuchsvorschrift

To a solution of 2-tert-butoxycarbonylamino-3-(1H-indole-3-yl)propionic acid (0.37 g, 1.2 mmol) in methylene chloride (15 ml) and dimethylformamid (5 ml) was added 1-hydroxy-7-azabenzotriazole (0.16 mg, 1.20 mmol) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.23 9, 1.20 mmol) and the mixture was stirred for 30 min. Then 4-benzylpiperidine-4-carboxylic acid N′,N′-dimethylhydrazide (0.26g, 1.0 mmol) and diisopropylethylamine (0.69 ml, 4.0 mmol) was added and the mixture was stirred overnight. Methylene chloride (100 ml) was added and the mixture was washed with saturated aqueous sodium hydrogencarbonate (20 ml), water (20 ml), dried (MgSO4), filtered and concentrated in vacuo. The obtained oil was chromatographed on silica (40 g) with methylene chloride/(10% ammonia in methanol) (9:1) to give 0.43 g of (2-(4-benzyl-4-(N′,N′-dimethylhydrazinocarbonyl)piperidine-1-yl)-1-(1H-indole-3-ylmethyl)-2-oxoethyl)carbamic acid tert-butyl ester as a colorless oil.
