実験手順
To 540 mg of 8-chloro-7-methoxy-4-(3,4-dimethoxyphenyl)-1,2,3,4-tetrahydroisoquinoline was added 11 ml of 48% hydrobromic acid, and the mixture was heated under reflux for 3 hours under an argon gas stream. After cooling, the crystals which separated out were collected by filtration and 520 mg of 8-chloro-7-hydroxy-4-(3,4-dihydroxyphenyl)-1,2,3,4-tetrahydroisoquinoline hydrobromide was obtained.
