Versuchsvorschrift

3.2 g of 5,6,7,8-tetrahydroisoquinoline and 0.7 g of potassium carbonate were mixed in 3 ml of acetonitrile and brought to 80° C. A solution of 3.4 g of disulfanediyldiethane-2,1-diyl dimethane sulfonate in 3 ml of acetonitrile was added in 10 min. Stirring was maintained for 8 h at 80° C. and then the reaction medium was brought back to ambient temperature, filtered, and concentrated under vacuum. 6 ml of dichloromethane were added and the solution was poured dropwise into 500 ml of ethyl ether. The oil that had been separated by settling out was reprocessed twice by diluting in 6 ml of methanol and adding to 500 ml of ethyl ether, and a final time by diluting in 6 ml of dichloromethane and adding to 500 ml of ethyl ether. After drying under vacuum, 5.2 g of brown solid were recovered. The analyses were in compliance with the expected structure.
