実験手順

A solution of 2.80 g (4.90 mmol) (R)-2-(4-benzyloxy-3,5-dimethyl-phenyl)-1-carboxy-ethyl 4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carboxylate (Example 1g), 1.80 g (5.61 mmol) TBTU and 3.10 mL (22.08 mmol) triethylamine in 30 mL DMF was stirred for 1 h at RT. Then 2.00 g (5.48 mmol) ethyl (4-piperazin-1-yl-piperidin-1-yl)-acetate were added. The reaction mixture was stirred for 1 h at RT, poured onto 150 mL 15% K2CO3 solution and extracted with 200 mL EtOAc. The organic phase was extracted with 150 mL of 10% citric acid solution, the aqueous phase was made alkaline with 15% K2CO3 solution and extracted with 200 mL EtOAc. The organic phase was concentrated by evaporation i. vac. and the residue was purified by chromatography (silica gel, EtOH).
