Procedure
Benzaldehyde (406 μl, 4 mmol), acetone (294 μl, 4 mmol), malononitrile (264 mg, 4 mmol) e ammonium acetate (462 mg, 6 mmol) were placed in a microwave tube and irradiated with microwaves (Solvent: none; Power: 150 W; Ramp time: 5 min; Heating time: 10 min; Temperature: 100° C.; Pressure: 175 psi; Stirring: on; Cooling: on). At the end of the microwave irradiation cycle, the solvent was removed under reduced pressure. The crude product was purified by flash chromatography on silica gel (petroleum ether/ethyl acetate=90/10) to obtain 2-amino-4-phenyl-6-methylnicotinonitrile in 40% yield.
