A mixture of 7-bromo-2-chloro-1,5-naphthyridine (F-31) (200 mg, 0.82 mmol, 1.0 eq) and morpholine (10 mL) was stirred in a sealed-tube at 140° C. overnight. The reaction mixture was cooled to RT, diluted with ethyl acetate (150 mL) and then washed with brine, dried over Na2SO4 and filtered. The filtrate was concentrated in vacuo to afford the desired product 7-bromo-2-morpholino-1,5-naphthyridine (F-32) (180 mg, 74.7% yield). ESI-MS m/z: 294.01 [M+H]+.
