4-Tert-Butylaniline → HCID 22171936, compound

Participants

Reaction Steps

Monoimine (6, 1.25 g, 4.34 mmol) and 4-tert-butylaniline (0.65 g, 4.34 mmol) were dissolved in 50 ml of toluene. To this solution, molecular sieves (4 Å) were added. After standing for 16 hours the mixture was filtered. The solvent was removed in vacuo. The residue was recrystallised from ethanol. Yield 0.44 g (24%) of mixed diimine (7, 96% purity by NMR). H-NMR (CDCl3) δ 8.51 (d, 1H, Py-Hm), 8.38 (d, 1H, Py-Hm), 7.91 (t, 1H, Py-Hp), 7.86 (d, 1H, ArH), 7.78 (d, 1H, ArH), 7.63 (d, 1H, ArH), 7.4-7.6 (m, 5H, ArH), 6.8-6.9 (m, 3H, ArH), 2.43 (s, 3H, Me), 2.37 (s, 3H, Me), 1.34 (s, 9H, But).
