2-chloro-1,8-naphthyridine (89 mg, 0.54 mmol), 5-(trans-3-aminocyclobutyl)-7,7-dimethyl-5H-pyrrolo[2,3-b]pyrazin-6(7H)-one (100 mg, 0.431 mmol), and cesium carbonate (202 mg, 0.620 mmol) were suspended in dry dimethylformamide (0.86 mL) under nitrogen and heated to 100 C. for 18 h. The mixture was cooled and extracted with ethyl acetate and water. The phases were separated and the organic was dried with magnesium sulfate before evaporating to dryness under reduced pressure. Purification using the ISCO (0-100% EtOAc in hexane), gave the desired 5-(trans-3-((1,8-naphthyridin-2-yl)amino)cyclobutyl)-7,7-dimethyl-5H-pyrrolo[2,3-b]pyrazin-6(7H)-one (32 mg, 0.089 mmol, 21% yield) as a light yellow solid. 1H NMR (300 MHz, CHLOROFORM-d) delta: ppm 1.45 (s, 6H) 2.42 (ddd, J=13.88, 9.28, 3.29 Hz, 2H) 3.44-3.62 (m, 2H) 5.22-5.38 (m, 2H) 6.71 (d, J=8.92 Hz, 1H) 7.16 (dd, J=7.82, 4.46 Hz, 1H) 7.79-7.98 (m, 2H) 8.11 (q, J=3.12 Hz, 2H) 8.84 (dd, J=4.38, 1.90 Hz, 1H).
15936-10-4 2-Chloro-1,8-naphthyridine 5152838, anaphthyridine compound, is more and more widely used in various fields.
