Participants

Reaction Conditions

Reaction Steps

To a suspension of 2 g of 5-iodo-6-methylpyridine-2-amine in 15 mL of dimethoxyethane are added 1.3 mL of ethyl bromopyruvate. The reaction mixture is stirred at 20° C. for 16 hours and then concentrated to dryness, taken up in 15 mL of ethanol, refluxed for 2.5 hours and finally concentrated under reduced pressure. The residue is taken up in a mixture of dichloromethane and saturated sodium bicarbonate solution. The organic phase is dried over magnesium sulfate and concentrated to dryness under reduced pressure to give 2.77 g of ethyl 6-iodo-5-methyl(pyrid-2-yl)imidazo[1,2-a]pyridine-2-carboxylate in the form of a beige-coloured solid.
