실험 절차

N-Propylphosphonic acid anhydride, cyclic trimer (0.356 ml; 0.610 mmol) is added to a mixture of 1,5-dimethyl-6-oxo-1,6-dihydro-pyridine-3-carboxylic acid D1 (85.000 mg; 0.508 mmol), N4-Benzyl-6-morpholin-4-yl-pyridine-3,4-diamine E-2.3 (133.000 mg; 0.468 mmol) and triethylamine (0.176 ml; 1.271 mmol) in THF (3.000 ml). The reaction mixture is stirred overnight (16 h) at RT. The reaction is quenched with 1M NaOH (2 ml) and diluted with water, then extracted twice with ethyl acetate. The organic layer is dried over Na2SO4 and concentrated in vacuum. The residue is purified on silica chromatography Combiflash (Column: Redisep Rf, 12 g; gradient: DCM/MeOH=100%/0% to 90%/10%; flow rate=30 ml/min; 28 column volumes; detection wavelength: 254 nm). The product containing fractions are combined and concentrated under reduce pressure.
