Water → 2-Methyl-8-(3-methyl-4-pyridylmethoxy)-3-(2-propynyl)imidazo[1,2-a]pyridine

Participants

Reaction Steps

Potassium carbonate (0.52 g) was added to a solution of 8-hydroxy-2-methyl-3-(2-propynyl)imidazo[1,2-a]pyridine (0.5 g) and 4-chloromethyl-3-methylpyridine (0.53 g) in N,N-dimethylformamide (10 ml). The mixture was stirred under a nitrogen atmosphere for 5 hours at room temperature and then poured into water. The resulting precipitates were collected by filtration and recrystallized from ethyl acetate to give 2-methyl-8-(3-methyl-4-pyridylmethoxy)-3-(2-propynyl)imidazo[1,2-a]pyridine (0.58 g).
