Procedure

To a solution of 4-(4-(cyclopropylmethoxy)-2,6-dimethylphenyl)thiazol-2-amine (4-5, 0.410 g, 1.51 mmol) in CH2Cl2 (10 mL) was added triethylamine (1.0 mL, 7.2 mmol) followed by isonicotinoyl chloride hydrochloride (0.470 g, 2.62 mmol). The reaction mixture was stirred at room temperature overnight. The solution was concentrated under reduced pressure and added with water. The resultant precipitate was filtered, and recrystallized in toluene to give N-{4-(4-(cyclopropylmethoxy)-2,6-dimethylphenyl)thiazol-2-yl}isonicotinamide (4, 0.41 g) as light yellow solids in 72% yield: 1H NMR (500 MHz, DMSO-d6) δ 13.0 (s, 1 H), 8.80 (d, J=4.9 Hz, 2 H), 7.99 (d, J=6.0 Hz, 2 H), 7.10 (s, 1 H), 6.68 (s, 2 H), 3.81 (d, J=7.0 Hz, 2 H), 2.06 (s, 6 H), 1.21 (s, 1 H), 0.57 (d, J=6.5 Hz, 2 H), 0.32 (d, J=5.7 Hz, 2 H). ESI-MS: m/z 380.3 (M+H)+.
