4-Methoxyphenol → 1,2-Benzenedicarbonitrile, 4-(4-methoxyphenoxy)-

Participants

Reaction Steps

A mixture of 4-nitro-phthalonitrile (4.00 g), 4-methoxy-phenol (3.46 g) and potassium carbonate (6.39 g) in acetone (64 ml) was heated to reflux for 2 h. Reaction mixture was cooled and filtered. Filtrate was concentrated and the residue was dissolved in ethyl acetate (100 ml). The solution was washed with NaOH (1 N, 50 ml), water, and then brine. The organic layer was dried over magnesium sulfate, filtered, and concentrated to give the product (6.14 g). 1H NMR (200 MHz, CDCl3) δ 6.70 (d, J=7.8 Hz, 1H), 7.21 (m, 2 H), 6.96 (m, 4 H), 3.84 (s, 3 H).
