Reaction Steps

Malononitrile (132 mg, 2 mmol) was dissolved in ethanol (6 mL), and 5-formylsalicylic acid (332 mg, 2 mmol) was added. After cooling with ice bath, benzylamine (0.1 mL) was added and the mixture was stirred at room temperature for 2 hours. The separated yellow crystal was filtered and recrystallized (ethanol) to give the title compound (139.9 mg, 32.7%) as a light yellow solid.
