Procedure
640 mg of 7-methoxy-4-(3,4-dimethoxyphenyl)-1,2,3,4-tetrahydroisoquinoline was dissolved in 13 ml of 48% aqueous hydrogen bromide, and the mixture was heated under reflux under an argon gas stream for 3 hours. The reaction solution was cooled, and crystals which separated out were collected, affording 580 mg of 7-hydroxy4-(3,4-dihydroxyphenyl)-1,2,3,4,-tetrahydroisoquinoline hydrobromide.
