Procedure

Stir a solution of [3-(2,4-dichlorophenyl)-2,5-dimethylimidazolo[5,4-b]pyridin-7-yl](4-methoxybenzyl)amine (4.23 g, 10 mmol), anisole (3.2 mL, 29.6 mmol), trifluoroacetic acid (80 mL), and concentrated sulfuric acid (2 mL) at ambient temperature for 14 h. Add the resulting mixture dropwise to ice-water and dilute with NaHCO3. Filter the resulting precipitate and wash thoroughly with water to obtain the title compound as a brown solid.

Workup

  1. filtrationFilter the resulting precipitate
