A mixture of 150 mg (0.21 mmol) ethyl [1′-((R)-3-(3,4-diethyl-phenyl)-2-{[4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carbonyl]-amino}-propionyl)-[4,4′]bipiperidinyl-1-yl]-acetate, 20 mL THF and 2.5 mL 0.1 M NaOH was stirred for 12 h at RT. The organic solvent was eliminated under reduced pressure and the pH of the reaction mixture was adjusted to exactly 7.0 by the addition of 0.1 M HCl. The precipitate was suction filtered, washed with a little water and dried.
