Procedure

A solution of 40 mg (0.08 mmol) (R)-2-(4-methoxy-3,5-dimethyl-phenyl)-1-carboxy-ethyl 4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carboxylate, 29 mg (0.09 mmol) TBTU and 14 μL (0.10 mmol)triethylamine in 1 mL DMF was stirred for 1 h at RT. Then 15 mg (0.09 mmol) 1-(tetrahydropyran-4-yl)-piperazine was added and the mixture was stirred for a further 16 h at RT. The reaction solution was purified by HPLC without any further working up; the fractions containing the product were combined and lyophilised.
