1-methyl-1,2,3,4-tetrahydroisoquinolin-7-ol;hydrobromide

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Hydrobromic acid (48%, 46 mL) was added to the 7-methoxy-1-methyl-1,2,3,4-tetrahydro-isoquinoline (2.55 g) and the resulting mixture was heated at reflux for 16 h. Evaporation of the hydrobromic acid, followed by trituation with ethyl acetate (3×) afforded 1-methyl-1,2,3,4-tetrahydro-isoquinolin-7-ol hydrogen bromide (3.04 g). the resulting mixture was heated at reflux for 16 h Evaporation of the hydrobromic acid

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
