1,2,3,4-Tetrahydroisoquinoline → Ethyl (3,4-dihydro-1H-isoquinolin-2-yl)acetate

Participants

Reaction Steps

To a solution of 40 (1.33 g, 10.0 mmol) in acetonitrile (50 mL) were sequentially added potassium carbonate (5.53 g, 40.0 mmol) and ethyl bromoacetate (1.67 g, 10.0 mmol). The reaction mixture was stirred at room temperature overnight, then partitioned between EtOAc (200 mL) and water (150 mL). The organic layer was dried (MgSO4) and concentrated under reduced pressure to give 90 (2.1 g, 99%).
