실험 절차

The starting appropriately substituted tetrahydroisoquinolines of the formula (A) are conveniently prepared by standard reactions well known in the chemical arts as shown below: ##STR3## 2-Acetyl-7-chlorosulfonyl-1,2,3,4-tetrahydroisoquinoline, which is prepared by acylating and then chlorosulfonating 1,2,3,4-tetrahydroisoquinoline, is reduced to 2-acetal-7-mercapto-1,2,3,4-tetrahydroisoquinoline employing stannous chloride in acetic acid-hydrochloric acid mixture. The 2-acetyl-7-mercapto-1,2,3,4-tetrahydroisoquinoline is then condensed with the appropriately substituted α-bromo acetophenone to afford 2-acetyl-7-benzoylmethylthio-1,2,3,4-tetrahydroisoquinoline (B) which is then oxidized with m-chloroperbenzoic acid and hydrolyzed to yield the desired 7-benzoylmethylsulfonyl-1,2,3,4-tetrahydroisoquinoline (A). Bis(chlorosulfonyl)imide is prepared from chlorosulfonic acid and chlorosulfonylisocyanate.
