実験手順
4-Fluorobenzonitrile (7.0 g, 58 mmol) and 2-methylpropane-1,2-diamine (14 g, 160 mmol) were heated in a sealed vial in a microwave reactor (Biotage) at 180° C. for 25 minutes in two batches. Each batch was dissolved in methanol (50 mL) and then concentrated with silica to dryness. Flash chromatography on silica of each batch with neat acetonitrile and 2% triethylamine in acetonitrile as eluents gave 4-(2-amino-2-methylpropylamino)benzonitrile (9.58 g, 88% combined yield) as a white solid.
