Sodium Hydroxide → 2-(3-Formyl-2-methoxyphenoxy)-6-(trifluoromethyl)nicotinonitrile

Participants

Reaction Steps

2-Chloro-6-(trifluoromethyl)nicotinonitrile (0.34 g, 1.6 mmol), 3-hydroxy-2-methoxybenzaldehyde (0.25 g, 1.6 mmol) and potassium fluoride (0.29 g, 4.9 mmol) were heated with stirring in dry DMF (4 mL) at 120° C. for 3 h. The reaction mixture was cooled, poured into 1N sodium hydroxide solution and extracted with ethyl acetate. The ethyl acetate layer was separated, washed with 1N sodium hydroxide solution (3×), water (3×), brine (1×), and dried over MgSO4. After filtration, the solvent was removed in vacuo to yield 2-(3-formyl-2-methoxyphenoxy)-6-(trifluoromethyl)nicotinonitrile (0.50 g, 94%) as a yellow solid.
