실험 절차

A solution of N-(2-(5-fluoropyridin-3-yl)-4-methylthiazol-5-yl)-N-methylpiperidine-3-carboxamide (250 mg, 0.75 mmol), DMAP (91 mg, 0.75 mmol), potassium carbonate (310 mg, 2.243 mmol), and 2-methylpentanoyl chloride (201 mg, 1.495 mmol) in DCE (10 mL) was heated at 80° C. for 6 h. The cooled contents were diluted with water:dichloromethane (1:1, 20 mL) and the organic layer was collected and concentrated. The residue was purified via reversed phase chromatography (0 to 100% acetonitrile/water) to furnish the title compound as a clear oil (207 mg, 64%): 1H NMR (400 MHz, CDCl3) δ 8.89 (s, 1H), 8.54 (d, J=2.2 Hz, 1H), 7.96 (dt, J=9.0, 2.2 Hz, 1H), 4.63-4.59 (m, 1H), 3.92-3.78 (m, 1H), 3.42 (s, 3H), 2.66-2.48 (m, 4H), 2.38 (s, 3H), 1.89-1.73 (m, 2H), 1.71-1.68 (m, 2H), 1.38-1.17 (m, 4H), 1.08-1.01 (m, 3H), 0.97-0.86 (m, 3H); ESIMS m/z 433 (M+1).
