Reaction Steps
7-Nitro-1,2,3,4-tetrahydroisoquinoline (5.78 g) was dissolved in ethanol (400 ml), triethylamine (7.8 ml) and ethyl bromoacetate (4.5 g) were added, and the mixture was heated and refluxed for 1 hour. Most of the solvent was distilled off under reduced pressure, concentrated residue was extracted with ethyl acetate and the extracted solution was dried with anhydrous magnesium sulfate. The solvent distilled off under reduced pressure and the crude product obtained was purified by silica gel column chromatography using a solvent mixture, ethyl acetate:n-hexane=1:3, as a developer. The compound obtained was treated with a hydrochloric acid/dioxane solution to obtain ethyl 7-nitro-1,2,3,4-tetrahydro-isoquinoline-2-acetate hydrochloride (4.2 g).
