Reaction Steps

Ethoxyacetyl chloride (6 mL, 53.8 mmol) was added to a suspension of 3-aminoquinoline-4-thiol (4.6 g, 26.1 mmol) in ethoxyacetic acid (50 mL). The reaction mixture was heated at 60° C. overnight. The reaction mixture was concentrated under vacuum to remove a portion of the ethoxyacetic acid. The residue was combined with water (100 mL) and a precipitate formed. The mixture was made basic with 50% sodium hydroxide. The precipitate was isolated by filtration, washed with water and then dried to provide 2-(ethoxymethyl)thiazolo[4,5-c]quinoline as a fluffy green solid.
