Under a nitrogen atmosphere 55 mg (0.30 mmol) 1-methyl-4-piperidin-4-yl-piperazine was added to a solution of 151 mg (0.25 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, 104 mg (0.27 mmol) HATU and 47 μL (0.27 mmol) ethyldiisopropylamine in 5 mL DMF and the reaction mixture was stirred for 3 h at RT. The reaction solution was evaporated down i.vac. and the residue was purified by chromatography (silica gel, DCM/MeOH/NH3 80:20:2).
