実験手順

To a solution of 537 mg (1.000 mmol) 2-(4-amino-3-chloro-5-trifluoromethyl-benzyl)-4-oxo-4-[4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidin-1-yl]-butyraldehyde (Intermediate product 36) in 10 mL DMF was added tert. butyl 4-[(2-amino-phenylamino)-methyl]-piperidin-1-carboxylate (Intermediate product 34) and the mixture was stirred for 16 hours in an atmosphere of air at RT. The reaction mixture was poured onto ice water, the precipitate formed was filtered off, washed with water and dried i. vac. (Yield: 790 mg, 96% of theory). 1 mL of TFA was added to a solution of 580 mg (0.705 mmol) of the crude product in 10 mL dichloromethane and the mixture was stirred for 16 hours at RT. The reaction mixture was diluted with dichloromethane, the org. phase was washed with sat. aqueous sodium bicarbonate solution, dried over sodium sulphate and evaporated i. vac. The residue was dissolved in 3.5 mL DMF and purified by HPLC-MS (Zorbax Bonus C18 amide-phase 5 μm, gradient 0.15% formic acid in water/acetonitrile 10/90→90/10 v/v) and then lyophilised.
