반응 단계

To a suspension of 2.15 g of methyl 6-amino-5-[(2-fluorobenzyl)oxy]nicotinate in 43 ml of ethanol was added 1.09 ml of bromoacetone, followed by stirring at 80° C. for 4 hours. To the reaction mixture was added 1.09 ml of bromoacetone, followed by stirring at 80° C. for 4 hours. To the reaction mixture was added a saturated aqueous sodium hydrogen carbonate solution, and the solvent was evaporated under reduced pressure, followed by extracting with ethyl acetate and washing with saturated brine. After drying over anhydrous magnesium sulfate and then filtering, the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography to obtain 1.39 g of methyl 8-[(2-fluorobenzyl)oxy]-2-methylimidazo[1,2-a]pyridine-6-carboxylate.
