Reaction Steps

A mixture of 4-(trifluoromethyl)pyrazole (116 mg, 0.85 mmol), 1-(6-chloropyridin-3-yl)butan-1-one (130 mg, 0.71 mmol), and potassium carbonate (294 mg, 2.12 mmol) was stirred 4 h at 50° C. The mixture was cooled to room temperature and stirred overnight. The mixture was partitioned between ethyl acetate and water. The organic layer was dried over MgSO4 and concentrated under reduced pressure. The residue was purified by silica gel chromatography to give 1-(6-(4-(trifluoromethyl)-1H-pyrazol-1-yl)pyridin-3-yl)butan-1-one (200 mg) as a colorless solid. 1H NMR (400 MHz, CDCl3) δ 8.97-8.99 (m, 1H), 8.90-8.91 (m, 1H), 8.39 (dd, J=8.5, 2.4 Hz, 1H), 8.08 (dd, J=8.58, 0.78 Hz, 1H), 7.93 (s, 1H), 2.94 (t, J=7.4 Hz, 2H), 1.74-1.85 (m, 2H), 1.02 (t, J=7.4 Hz, 3H).
