Procedure

0.30 mL (2.16 mmol) triethylamine were added to a mixture of 300 mg (0.54 mmol) (R)-2-(4-amino-3-chloro-5-trifluoromethyl-phenyl)-1-carboxy-ethyl 4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carboxylate (Example 1f), 220 mg (0.64 mmol) ethyl([1,4′]bipiperidinyl-4-yloxy)-acetate (Example A13c) and 200 mg (0.62 mmol) TBTU in 3 mL DMF and the reaction mixture was stirred for 4 h at RT. Ice and saturated NaHCO3 solution were added and the precipitate was filtered off. This was taken up in DCM and a little EtOH and dried over Na2SO4. After elimination of the desiccant and solvent the residue was purified by HPLC; the fractions containing the product were combined and lyophilised.
