Procedure

A solution of 120 mg (0.22 mmol) (R)-1-carboxy-2-(7-methyl-1H-benzimidazol-5-yl)-ethyl 4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carboxylate, 85 mg (0.27 mmol) TBTU and 120 μL (0.86 mmol) triethylamine in 10 mL THF and 1 mL DMF was stirred for 1 h at RT, then combined with 90 mg (0.27 mmol) 1-benzyl-4-piperidin-4-yl-piperazine (used as the bishydrochloride salt) and stirred overnight at RT. The reaction solution was combined with 1 mL semisaturated NaHCO3 solution and extracted with 100 mL EtOAc. The organic phase was dried over Na2SO4, filtered and evaporated down i.vac.
