Procedure
30 mg (0.29 mmol) 2-hydroxy-N,N-dimethyl-acetamide were added at RT to a solution of 200 mg (0.25 mmol) 1′-{(R)-3-(4-benzyloxy-3,5-dimethyl-phenyl)-2-[4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carbonyloxy]-propionyl}-1,4′-bipiperidinyl-4-carboxylic acid (Example 6.1a), 90 mg (0.28 mmol) TBTU and 80 μL (3.73 mmol) triethylamine in 1.8 mL DMF and this was stirred for 20 h at RT. The reaction mixture was poured onto saturated NaHCO3 solution, the precipitate formed was suction filtered and dried. Further purification was carried out by HPLC, the fractions containing the product were combined and lyophilised.
