실험 절차

Combine 4-methoxybenzonitrile (50.0 g, 376 mmol), potassium t-butoxide (84.2 g, 752 mmol), propionitrile (62.0 g, 1.130 mmol) and toluene (1,880 mL); and stir for 72 h. Dilute with satd NaHCO3 and extract with EtOAc. Evaporate the organic solution and crystallize from hexane/EtOAc to afford 3-amino-3-(4-methoxyphenyl)-2-methylacrylonitrile. Yield: 35.1%. ES-MS: m/e 189.2 (m+1).
