Procedure

A solution of 118 mg (4.9 mmol) LiOH in 5 mL water was added to a solution of 2.0 g (3.3 mmol) of (R)-2-(3,5-dibromo-phenyl)-1-methoxycarbonyl-ethyl 4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carboxylate in 12.5 mL THF and the mixture was stirred for 2 h at RT. The reaction mixture was evaporated down i. vac., the residue was combined with water and TBME, the aqueous phase was adjusted to pH 2-3 with conc. HCl and extracted with DCM. The combined organic phases were washed with saturated NaCl solution, dried over Na2SO4 and evaporated to dryness i. vac.
