Sodium Hydroxide → 3-Methoxy-2-methylbenzonitrile

Participants

Reaction Steps

Hydroxylamine hydrochloride (0.75 g, 11 mmol) was added to 3-methoxy-2-methylbenzaldehyde (1.25 g, 8.32 mmol) in formic acid (89-91%) (10 ml), and the mixture heated to reflux for 40 min., cooled, diluted with ice-cold water, basified with 10% aqueous sodium hydroxide solution and extracted with diethyl ether. The organic extract was washed with saturated aqueous sodium chloride (50 ml), dried over magnesium sulphate and evaporated. The residue was purified by flash chromatography over silica gel eluting with 5% diethyl ether in hexane to afford the product as a white solid (0.98 g). M+ 147; 360 MHz 1H n.m.r (CDCl3) 7.26-7.17 (2H, m), 7.02 (1H, d, J 7.9 Hz), 3.86 (3H, s), 2.41 (3H, s).
