Participants

Reaction Steps

To 3-chloro-N-(3-chloro-1-(pyridin-3-yl)-1H-pyrazol-4-yl)-N-ethylpropan amide (0.500 g, 1.60 mmol) in acetone (8 mL) was added sodium iodide (0.359 g, 2.40 mmol). The reaction was heated to reflux for 24 hours. The reaction product was filtered and concentrated to provide N-(3-chloro-1-(pyridin-3-yl)-1H-pyrazol-4-yl)-N-ethyl-3-iodopropanamide (0.363 g, 0.898 mmol), which was used immediately without further purification. To 3-(but-3-en-1-yl)pyrrolidin-2-one (0.125 g, 0.898 mmol) dissolved in DMF (4.49 ml) was added sodium hydride (60% in mineral oil, 0.0360 g, 0.898 mmol). The reaction stirred for 45 minutes. Then, N-(3-Chloro-1-(pyridin-3-yl)-1H-pyrazol-4-yl)-N-ethyl-3-iodopropanamide (0.363 g, 0.898 mmol) was added as a solution in DMF (2 mL). The reaction mixture was allowed to stir at room temperature overnight. The reaction product was poured into water, extracted with diethyl ether, and washed with brine. The organics were dried and concentrated to give an oil that was purified by flash column chromatography using 0-60% acetone/hexanes as eluent providing the title compound as a clear, colorless oil. (0.257 g, 69%).
