Versuchsvorschrift

Triethylamine (33 μL, 0.24 mmol) and 3-[(2,5-dioxopyrrolidin-1-yl)oxy]-3-oxopropane nitrile (prepared as described in BE875054(A1), 51 mg, 0.28 mmol) were added to a solution of (R)-3-(4-(piperidin-3-ylamino)pyrimidin-2-ylamino)pyridin-2(1H)-one (Preparation 19c, 67 mg, 0.23 mmol) in dichloromethane (3 mL). The reaction mixture was stirred at ambient temperature for 24 hours and solvent was evaporated. Water was added and the mixture was extracted with dichloromethane. The organic layer was dried (MgSO4), evaporated under reduced pressure and the residue was purified by reverse phase chromatography (C-18 silica from Waters©, water/acetonitrile/methanol as eluents [0.1% v/v formic acid buffered] 0% to 100%) to give the title compound (11 mg, 12%) as a solid.
