Hydrochloric Acid → 8-(cyclohexylmethoxy)-2-methyl-N-(2-oxoethyl)imidazolo[1,2-a]pyridine-3-carboxamide

Participants

Reaction Steps

To a solution of 200 mg of 8-(cyclohexylmethoxy)-N-(2,2-dimethoxyethyl)-2-methylimidazolo[1,2-a]pyridine-3-carboxamide in 2 mL of dioxane was added 6 M hydrochloric acid, followed by stirring for 7 hours. To the reaction mixture were added saturated brine and ethyl acetate to carry out a layer separation operation. To the obtained aqueous layer was added a 1 M aqueous sodium hydroxide solution, and the resulting solid was collected by filtration and dried to obtain 165 mg of 8-(cyclohexylmethoxy)-2-methyl-N-(2-oxoethyl)imidazolo[1,2-a]pyridine-3-carboxamide.
