Participants

Reaction Steps

Combine prop-1-en-2-yl(2-fluoro-4-methyl-5-(2-methyl-7-(methylamino)-1,6-naphthyridin-3-yl)phenyl)carbamate (2.5 g, 6.6 mmol), 3-fluoro-3-methylbutan-1-amine diacetate (1.8 g, 7.9 mmol), and N-methylpyrrolidine (2.7 mL, 26.0 mmole) in THF (50 mL) and heat at 50° C. overnight. Evaporate under reduced pressure and partition between NaHCO3 and EtOAc. Wash the organic layer with brine, dry over Na2SO4, concentrate in vacuo, and purify by silica gel chromatography (50-100% EtOAc/DCM) to obtain the title compound (2.0 g, 71%). 1H NMR (400 MHz, DMSO-d6): δ 8.82 (s, 1H), 8.33 (s, 1H), 7.93 (d, J=8 Hz, 1H), 7.83 (s, 1H), 7.16 (d, J=8 Hz, 1H), 6.73 (m, 1H), 6.56 (m, 1H), 6.52 (s, 1H), 3.15 (m, 2H), 2.82 (d, J=5 Hz, 3H), 2.27 (s, 3H), 1.94 (s, 3H), 1.73 (m, 2H), 1.30 (d, J=21.6 Hz, 6H); MS (ESI) m/z: 428.2 (M+H+).
