To (S)-tert-butyl 3-aminopyrrolidine-1-carboxylate (0.776 g, 4.17 mmol) in N-methyl-2-pyrrolidinone (12 mL) at 0° C. was added NaH (0.139 g, 3.47 mmol). The mixture was stirred for 5 minutes. Next, 6,8-dibromo-1,7-naphthyridine (1 g, 3.47 mmol) was added and the reaction mixture was stirred at RT for 5 minutes and then heated at 135° C. for 30 minutes in a microwave reactor. The reaction mixture was diluted with water and extracted with EtOAc (2×). The organic layers were combined, dried over Na2SO4, and concentrated. The crude product was purified using silica column chromatography eluting with a gradient of 0-75% EtOAc in hexane over a 45 minute period to give the title compound as a yellow solid (1.3 g, 95%).
