Condition B: The reaction conditions were identical except the quantity of amine was increased to 7-8 equiv, KF-alumina was used in the ratio of 3:2, and the solid mixture was heated at 135 °C for 3 h. Pure bis-amines were obtained by chromatography over silica gel and elution with EtOAc-light petroleum (1:9). The spectral data were consistent with the assigned structures.
