Reaction Steps

A mixture of 2-chloro-N-(4-mesitylthiazol-2-yl)isonicotinamide (200 mg, 0.60 mmol, 1.0 equiv) and piperidine (0.70 mL, 6.7 mmol, 12 equiv) in methylpyrrolidone (6.0 mL) was stirred at 150° C. for 16 h. The mixture was poured into icy H2O (10.0 mL) and the resultant solids were filtered. The solids were purified by column chromatography on silica gel (15% EtOAc in hexanes as eluant) to provide N-(4-mesitylthiazol-2-yl)-2-(piperidin-1-yl)isonicotinamide (87.2 mg, 0.20 mmol) as yellow solids in 38% yield: 1H NMR (CDCl3, 500 MHz) δ 8.29 (d, J=5.1 Hz, 1 H), 7.15 (s, 1 H), 6.83-6.90 (m, 3 H), 6.79 (s, 1 H), 3.61-3.63 (m, 4 H), 2.31 (s, 3 H), 2.08 (s, 6 H), 1.57-1.67 (m, 6 H); ESI-MS: m/z 407.2 (M+H)+.
