0.26 mL (0.13 mmol) 0.5 M LiOH solution were added to 50.0 mg (0.06 mmol) ethyl(S)-4-{(R)-3-(4-amino-3-chloro-5-trifluoromethyl-phenyl)-2-[4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carbonyloxy]-propionyl}-1-(1-methyl-piperidin-4-yl)-piperazine-2-carboxylate in 0.8 mL THF and the reaction mixture was stirred overnight at RT. To complete the reaction another 50 μL (0.1 mmol) 0.5 M LiOH solution were added, it was stirred for another 4 h at RT and then the reaction mixture was purified by HPLC without working up; the fractions containing the product were combined and lyophilised.
