실험 절차

A solution of 15 mg (0.63 mmol) LiOH in 5 mL water was added to a solution of 180 mg (0.25 mmol) (R)-2-(4-ethoxycarbonylmethoxy-1,4′-bipiperidinyl-1′-yl)-1-(4-hydroxy-3,5-dimethyl-benzyl)-2-oxo-ethyl 4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carboxylate in 15 mL THF and the reaction mixture was stirred for 4 h at RT. 0.66 mL of 1 M HCl were added and the mixture was concentrated by evaporation i. vac. The residue was taken up in a little DCM/MeOH (7:3) and filtered through silica gel. The filtrate was concentrated by evaporation i. vac., the residue was triturated with diethyl ether, suction filtered and dried.
