実験手順
The method described in Part E of Examples 1 through 4 was used to treat 1,5-dimethyl-1H-pyrazole-3-carboxamide (5.0 g, 36 mmol) with phosphorous oxychloride (20 mL) to afford 3.9 g of 1,5-dimethyl-1H-pyrazole-3-carbonitrile. A small portion was recrystallized from hexane to provide the following data.
