Procedure

64 mg (0.20 mmol) TBTU and 28 μL (0.20 mmol) triethylamine were added to a solution of 100 mg (0.18 mmol) (R)-2-(4-amino-3-chloro-5-trifluoromethyl-phenyl)-1-carboxy-ethyl 4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carboxylate in 1 mL DMF and stirred for 10 min at RT. 45 mg (0.20 mmol) ethyl (R)-1-piperidin-4-yl-pyrrolidine-2-carboxylate were added to the reaction mixture and this was shaken overnight at RT. After filtration through a syringe filter the reaction solution was purified by HPLC without further working up. The fractions containing the product were combined and freeze-dried.
