Procedure

A solution of 2.6 mg (0.11 mmol) LiOH in 1 mL water was added to a solution of 50 mg (0.07 mmol) (R)-2-[4-(2-ethoxycarbonyl-ethyl)-1,4′-bipiperidinyl-1′-yl]-1-(4-hydroxy-3,5-dimethyl-benzyl)-2-oxo-ethyl 4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carboxylate in 3 mL THF and the reaction mixture was stirred for 4 h at RT. The THF was eliminated in a nitrogen current and the crude product was purified by HPLC. The fractions containing the product were combined and lyophilised.
