Reaction Steps

5-Chloropyridin-2-amine (130 mg, 1.01 mmol), 3-chlorobenzaldehyde (171 mg, 1.21 mmol) and p-toluenesulfonic acid monohydrate (77 mg, 0.40 mmol) were combined in 2 mL of methanol to give a clear solution. To this solution was added 2-isocyanopropane (78 mg, 1.13 mmol) and the resulting clear solution was stirred at room temperature for 45 minutes. The mixture was filtered and the white solid was rinsed with methanol three times. The white solid was dried to afford [6-chloro-2-(3-chloro-phenyl)-imidazo[1,2-a]pyridin-3-yl]-isopropyl-amine (48 mg, 15%). MS: 320.0 and 322.0 [M+H]+; 1H-NMR (DMSO-d6): δ 8.53 (s, 1H), 8.23 (s, 1H), 8.13 (d, 1H), 7.52 (d, 1H), 7.46 (t, 1H), 7.32 (d, 1H), 7.20 (d, 1H), 4.92 (d, 1H), 3.20 (m, 1H), 1.04 (d, 6H).
