实验过程

A solution of 20 g (0.137 mol) 2-methyl-5,6,7,8-tetrahydro-naphthalene in 200 mL CHCl3 was added to 48 g (0.412 mol) chlorosulfonic acid at 0° C. After 2 hrs at room temperature the solution was slowly poured onto ice. The organic phase was washed, dried and concentrated to give 32 g 2-methyl-5,6,7,8-tetrahydro-naphthalene-sulfonic acid chloride used directly for the subsequent reaction.
