Reaction Steps

To a solution of 4-(2,6-dimethyl-4-(pyrimidin-2-yloxy)phenyl)thiazol-2-amine (6-3, 0.23 g, 0.77 mmol) in THF (3.9 mL) was added triethylamine (0.23 g, 2.30 mmol) followed by isonicotinoyl chloride hydrochloride (0.27 g, 1.52 mmol). The reaction mixture was heated at 60° C. overnight. The solution was concentrated under reduced pressure, added with water, and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous MgSO4(s), and concentrated under reduced pressure. The resultant precipitate was recrystallized in MeOH to give N-{4-(2,6-dimethyl-4-(pyrimidin-2-yloxy)phenyl)thiazol-2-yl}isonicotinamide (6, 0.12 g) as yellow solids in 38% yield: 1H NMR (500 MHz, CDCl3) δ 8.75 (d, J=6.0 Hz, 2 H), 8.58 (d, J=4.5 Hz, 2 H), 7.65 (d, J=6.0 Hz, 2 H), 7.04 (t, J=4.8 Hz, 1 H), 6.83 (s, 1 H), 6.70 (s, 2 H), 3.47 (s, 3 H), 1.97 (s, 6 H). ESI-MS: m/z 403.8 (M+H)+.
