Procedure

410 mg (1.20 mmol) ethyl 3-[1,4′]bipiperidinyl-4-yl-propionate (used as the bis-hydrochloride salt) were added at RT to a solution of 500 mg (1.04 mmol) (R)-2-(4-hydroxy-3,5-dimethyl-phenyl)-1-carboxy-ethyl 4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carboxylate (Example 1h), 385 mg (1.20 mmol) TBTU and 0.48 mL (3.40 mmol) triethylamine in 10 mL DMF and the mixture was stirred for 2 h. The reaction mixture was purified by HPLC without any further working up. The fractions containing the product were combined, concentrated by evaporation i.vac. and the residue was stirred with saturated NaHCO3 solution. The precipitate formed was filtered off and dried.
