A thick precipitate appeared within 5 min, and the mixture was stirred overnight (even if complete within minutes). Dilution with CH2Cl2 (50 mL), washing (1120; brine), drying (MgSO4), and evaporation afforded the crude product, which was filtered over silica gel (AcOEt:cyclohexane 1:1) to afford 1.15 g (86%) of the title bisallylamine, which was used in the next step without further purification.
