실험 절차

To a solution, ice cooled, of 1-(3,4-dichlorophenyl)-1H-pyrazol-3-amine (0.36 g, 1.59 mmol) and triethylamine (0.24 g, 2.38 mmol) in dry tetrahydrofurane (5 ml), 2-chloroacetyl chloride (0.2 g, 1.79 mmol) was added. The mixture was stirred overnight at room temperature, water added and the organic solvent evaporated in vacuo. The resulting suspension was filtered and dried yielding 0.45 g of 2-chloro-N-(1-(3,4-dichlorophenyl)-1H-pyrazol-3-yl)acetamide as a beige colour solid.
