Procedure

A mixture of 4-chloro-1-(2,4-dimethylphenyl)-1,6-dihydro-7H-pyrrolo[2,3-d]pyridazin-7-one (100 mg, 0.365 mmol), ethyl iodide (0.032 ml, 0.40 mmol), potassium carbonate (100 mg, 0.73 mmol) and DMF (1 ml) was stirred at room temperature for 7 hours. The mixture was diluted with water (50 ml) and extracted with ethyl acetate (50 ml). The extract was washed with water, dried over magnesium sulfate and concentrated in vacuo. The residue was purified by silica gel chromatography eluting with hexane/ethyl acetate (5:1) to give 102 mg (93%) of the title compound as crystals.
