Reaction Conditions

Reaction Steps

To a stirred solution of 2-methoxybenzonitrile (2.66 g, 20 mmol) and N-methylhydroxylamine hydrochloride (3.341 g, 40 mmol) in 2:1 water/ethanol (30 mL) was added sodium carbonate (2.332 g, 22 mmol) in small portions and the resulting pink solution stirred at 80° C. for 28 h. The reaction mixture was then concentrated and the residue stirred with CH2Cl2, filtered and concentrated to give crude product as a purple solid (3.3 g), which was used in the next step without further purification.
