Participants

Reaction Steps

8-Amino-2,3-dimethylimidazo[1,2-a]pyridine-6-carboxamide mesylate (1.0 g, 2.7 mmol), α-chloro-o-xylene (0.38 g, 2.7 mmol) and diisopropylethylamin (0.76 g, 5.9 mmol) in dimethylformamide (7 ml) were stirred at 50° C. for 7 h and at room temperature for 72 h. The solvent was evaporated and the residue was treated with a mixture of methylene chloride, water and a small amount of diisopropylethylamin. The solid that formed was isolated by filtration and washed with ethylacetate to give 0.11 g (13%) of the title compound.
