A mixture of 2-chloro-N-(1-(3,4-dichlorophenyl)-1H-pyrazol-3-yl)acetamide (0.22 g, 0.74 mmol), morpholine (71 mg, 0.81 mmol), potassium carbonate (0.22 g, 1.62 mmol) and sodium iodide (0.11 g, 0.74 mmol) in dry dimethylformamide (5 ml) was stirred and warmed at 100° C., overnight, in a dry nitrogen atmosphere. The solvent was evaporated in vacuo and water was added to the crude residue. The dark solid precipitated was filtered and dried yielding a crude product purified by crystallization in ethyl acetate, and 0.23 g of N-(1-(3,4-dichlorophenyl)-1H-pyrazol-3-yl)-2-morpholinoacetamide was obtained as a beige colour solid with m.p.=125-127° C.
