Procedure

A solution of 0.34 g (14.2 mmol) LiOH in 20 mL water was added to a solution of 3.38 g (6.76 mmol) of (R)-2-(3-chloro-4-methyl-phenyl)-1-methoxycarbonyl-ethyl 4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carboxylate in 30 mL THF and the reaction mixture was stirred for 7 h at RT. The mixture was evaporated down i.vac., diluted with 80 mL water, the aqueous phase was extracted twice with 50 mL diethyl ether, the aqueous phase was acidified with 4 M HCl and stirred for 30 min. The precipitated product was suction filtered, washed with water and dried.
