Versuchsvorschrift

50 mg (0.23 mmol) 1-(4-methyl-tetrahydropyran-4-yl)-piperazine (amine A1, used as the hydrochloride salt) were added to a solution of 90 mg (0.19 mmol) (R)-2-(4-hydroxy-3,5-dimethyl-phenyl)-1-carboxy-ethyl 4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carboxylate (Example 7h), 70 mg (0.22 mmol) TBTU and 70 μL (0.50 mmol) triethylamine in 1 mL DMF and the reaction mixture was stirred for 20 h at RT. Semisaturated NaHCO3 solution was added, the precipitate was filtered off and dried. The purification was carried out by chromatography (Alox, activity stage II-III, DCM/MeOH 30:1). After the solvent had been eliminated the residue was triturated with diethyl ether, suction filtered and dried.
