283 mg (1.00 mmol) ethyl 4-(4-piperazin-1-yl-piperidin-1-yl)-butyrate (Example A16b) were added to a mixture of 500 mg (0.90 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 (Example 1f), 321 mg (1.00 mmol) TBTU and 0.14 mL (1.00 mmol) triethylamine in 10 mL DMF and the reaction mixture was stirred for 2 h at RT. This was purified by HPLC without any further working up; the fractions containing the product were combined, evaporated down i. vac., the residue was stirred with saturated NaHCO3 solution, filtered and dried.
