実験手順
The starting tetrahydroisoquinolines of the formula (A), wherein Y is an appropriately substituted 7-benzeneaminosulfonyl radical, are conveniently prepared by standard reactions well known in the chemical arts as shown below: ##STR4## 2-Acetyl-1,2,3,4-tetrahydroisoquinoline was treated with chlorosulfonic acid to yield 2-acetyl-7-chlorosulfonyl-1,2,3,4-tetrahydroisoquinoline which is then reacted with an appropriately substituted aniline followed by treatment with dilute mineral acid to give the appropriately substituted tetrahydroisoquinoline (B). The starting tetrahydroisoquinolines of the formula (A), wherein Y is not a 7-benzeneaminosulfonyl radical, are conveniently prepared by standard reactions well known to the chemical arts.
