Reaction Steps

A mixture of 6-(4-isopropylpiperazin-1-yl)nicotinonitrile (2.3 g, 10 mmol), ethanol (25 mL), hydroxylamine hydrochloride (2.1 g, 30 mmol), potassium carbonate (2.2 g, 16 mmol) and water (5 mL) was stirred for 30 min at rt and then at reflux temperature for 3 h. The reaction mixture was left at rt for 2 days and then the solid formed was isolated by filtration. The solid was dried, boiled with ethanol (200 mL) and filtered hot to remove inorganic impurities. The filtrate was evaporated to give 2.0 g (76%) of N-hydroxy-6-(4-isopropylpiperazin-1-yl)nicotinamidine.
