Procedure

A solution of 1.4 mg (0.06 mmol) LiOH in 1 mL water was added to a solution of 30 mg (0.04 mmol) of (R)-1-(3,5-dibromo-4-hydroxy-benzyl)-2-(1′-ethoxycarbonylmethyl-4,4′-bipiperidinyl-1-yl)-2-oxo-ethyl 4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carboxylate (Example 138) in 3 mL THF and the reaction solution was stirred overnight at RT. The solvent was eliminated in the nitrogen current, the residue was taken up in 1 mL water, acidified with formic acid, the precipitate formed was removed by suction filtering and dried in vacuo.
