Reaction Steps

A reaction mixture of 4-(2-((2,8-dichloroquinolin-5-yl)oxy)ethyl)morpholine (81.5 mg, 0.25 mmol, 1 eq.), 2-amino-3-nitropyridine (41.3 mg, 0.27 mmol, 1.1 eq.), Pd(OAc)2 (1.1 mg, 2 mol %), XantPhos (2.9 mg, 2 mol %) and Cs2CO3 (228 mg, 2.8 eq.)) in t-BuOH (1 mL) was heated at 90° C. and stirred for 20 hours. The reaction mixture was then concentrated under reduced pressure and the resulting residue was diluted with ethyl acetate. The organic phase was washed with water, dried over MgSO4, filtered and concentrated under reduced pressure. The resulting residue was purified by column chromatography on silica gel to afford 8-chloro-N-(4-methyl-3-nitropyridin-2-yl)-5-(2-morpholinoethoxy)quinolin-2-amine (41 mg, 37%).
