Procedure

208 mg (0.82 mmol) ethyl [4,4′]bipiperidinyl-1-yl-acetate were added to a solution of 500 mg (0.82 mmol) of (R)-1-carboxy-2-(3,5-dibromo-4-hydroxy-phenyl)-ethyl 4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carboxylate, 315 mg (0.98 mmol) TBTU and 150 μL (1.06 mmol) triethylamine in 5 mL DMF and the reaction mixture was stirred overnight at RT. To complete the reaction a further 315 mg (0.98 mmol) TBTU, 150 μL (1.06 mmol) triethylamine and 208 mg (0.82 mmol) ethyl [4,4′]bipiperidinyl-1-yl-acetate were added and the mixture was again stirred overnight at RT. The reaction mixture was purified directly by HPLC without any further working up. The fractions containing the product were combined, evaporated down i.vac., neutralised with saturated NaHCO3 solution, the aqueous phase was extracted twice with 100 mL DCM and the combined organic phases were dried over Na2SO4. After the desiccant and solvent had been eliminated the residue was triturated with DIPE, suction filtered and dried in the air.
