Procedure

A solution of 100 mg (0.18 mmol) (S)-2-(4-amino-3-chloro-5-trifluoromethyl-benzyl)-4-oxo-4-[4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidin-1-yl]-butanoic acid, 65 mg (0.20 mmol) TBTU and 35 μL (0.18 mmol) triethylamine in 10 mL THF was stirred for 1 h at RT. Then 40 mg (0.24 mmol) 1-(tetrahydropyran-4-yl)-piperazine was added and the reaction solution was stirred overnight. 20 mL semisaturated NaHCO3 solution was added, extracted twice with 40 mL EtOAc and the combined organic phases were dried over Na2SO4. After the desiccant and solvent had been eliminated the residue was purified by HPLC; the fractions containing the product were combined and lyophilised.
