Reaction Steps
7-Hydroxy-1,2,3,4-tetrahydroisoquinoline hydrobromide (3 g) was dissolved in 1N aqueous sodium hydroxide solution (46 ml) and tetrahydrofuran (10 ml) and benzyl chlorocarbonate (2.45 g) was added. The mixture was stirred at room temperature for 30 min. The reaction mixture was extracted with chloroform and the organic layer was washed with saturated brine. The organic layer was dried over anhydrous sodium sulfate, and the solvent was evaporated. The residue was dried under reduced pressure to give the title compound (3.3 g).
