Versuchsvorschrift

A mixture of 2-{4-[3-(1-methyl-1H-imidazol-4-yl)-9-phenyl[1,2,4]triazolo[3,4-f]-1,6-naphthyridin-8-yl]phenyl}-5,8-dioxaspiro[3.4]octan-2-amine (142) (1.3 g, 2.49 mmol) and ethyl 1,3-dioxo-1,3-dihydro-2H-isoindole-2-carboxylate (0.37 g, 2.49 mmol) in CHCl3 (5 mL) was stirred at 70° C. for overnight. The mixture and DMF (5 mL) and DIPEA (0.44 mL, 2.49 mmol) were heated under microwave irradiation at 150° C. for 1 hour. The solvent was removed under reduced pressure, and to the residue was added MeOH. The resulting solid was collected by filtration. The solid (100 mg, 0.152 mmol) and 6N HCl in MeOH (1 mL) was stirred at room temperature for 1 hour. The mixture was quenched by aq. NaHCO3, extracted with CHCl3, dried (MgSO4), filtered, and concentrated under reduced pressure to yield (2-(1-{4-[3-(1-methyl-1H-imidazol-4-yl)-9-phenyl[1,2,4]triazolo[3,4-f]-1,6-naphthyridin-8-yl]phenyl}-3-oxocyclobutyl)-1H-isoindole-1,3(2H)-dione (1-13). MS (M+H)+: observed 616, calculated=616.
