실험 절차

N-Acetyl-1,2,3,4-tetrahydroisoquinoline (180 gm., 1.03 m.) was added slowly to 800 gms. (6.9 m.) of chlorosulfonic acid and stirred at -50° C. The solution was stirred at 25° C. for two days, poured onto crushed ice and extracted with ethyl acetate. The extract was washed, dried over anhydrous sodium sulfate and evaporated to yield crude N-acetyl-7-chlorosulfonyl-1,2,3,4-tetrahydroisoquinoline.
