Participants

Reaction Steps

Add potassium hydroxide (30.3 g, 225 mmol) to a solution of 2-methoxybenzonitrile (25.0 g, 187 mmol) and hydroxylamine hydrochloride (15.77 g, 225 mmol) in ethanol (500 mL) at room temperature under nitrogen and heat the mixture at reflux for 12 hours. Remove the solvent under reduced pressure, triturate the residue with ethyl acetate/hexanes (1:9, 300 mL) and collect by vacuum filtration to provide N-hydroxy-2-methoxybenzamidine (24.0 g, 91%).
