Methane → 3-(2,2-Dimethyl-propyl)-5-(4-fluoro-phenylethyl)-3H-imidazo[4,5-b]pyridin-2-ylamine

Participants

Reaction Steps

Add methanol (1,200 mL) to combined lots of 3-(2,2-dimethyl-propyl)-5-(4-fluoro-phenylethynyl)-3H-imidazo[4,5-b]pyridin-2-ylamine (37.30 g) and heat to reflux. Add activated charcoal (3.73 g, 10 wt %) and reflux for 1 h. Filter while slurry is hot, then add water (375 mL) to the filtrate with stirring at room temperature. Filter off solids, wash 2×100 mL water and dry under reduced pressure at 45-50° C. to provide 30.0 g (80%) of the desired compound.
