実験手順

51.75 ml. (0.78 mole) of chlorosulfonic acid was added dropwise with stirring to a solution of 20.7 g. (0.099 mole) 2-acetyl-8-chloro-1,2,3,4-tetrahydroisoquinoline in 25 ml. of methylene chloride at -70° C. To effectuate a solution of the reactants 10 ml. of dry chloroform was added and the reaction mixture stirred for one hour at -70° C. The reaction mixture was then refluxed at 40°-45° C. for 2 hours and then stirred at ambient temperature for about 16 hours. The reaction mixture was then cautiously poured onto one liter of ice. The crude reaction product was then extracted into methylene chloride (3×100 ml.), washed with saturated sodium chloride solution, dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated to dryness at reduced pressure to afford 2-acetyl-8-chloro-5-chlorosulfonyl-1,2,3,4-tetrahydroisoquinoline as whitish yellow solid with a melting point of 105°-115° C.
