Heat a mixture of prop-1-en-2-yl(5-(7-chloro-2-methyl-1,6-naphthyridin-3-yl)-2-fluoro-4-methylphenyl)carbamate (0.20 g, 0.518 mmol), 3,3,3-trifluoropropylamine hydrochloride (0.093 g, 0.622 mmol) and 1-methylpyrrolidine (0.068 mL, 0.648 mmol) in THF (5 mL) at 55° C. overnight. Cool to RT, add H2O, extract with EtOAc (2×), wash the combined organics with brine (2×), dry over MgSO4 and concentrate to dryness to afford the title compound (220 mg, 96%). 1H NMR (400 MHz, DMSO-d6): δ 9.23 (s, 1H), 8.53 (s, 1H), 8.31 (s, 1H), 8.01 (s, 1H), 7.97 (d, J=8.4 Hz, 1H), 7.23 (d, J=12.3 Hz, 1H), 6.75 (t, J=5.9 Hz, 1H), 3.58-3.02 (m, 2H), 2.42 (m, 2H), 2.41 (s, 3H), 1.95 (s, 3H).
