Versuchsvorschrift

To a solution of 7-methylthiomethoxy-1,2,3,4-tetrahydroisoquinoline-2-carboxylic acid benzyl ester (200 mg) in methylene chloride (4 ml) was dropwise added sulfuryl chloride (0.052 ml) with ice-cooling and under an argon atmosphere, and the mixture was stirred at the same temperature for 1 hour. The solvent was evaporated azeotropically with toluene and the residue was dried under reduced pressure to give the title compound (213 mg).
