Procedure
To a solution of commercially available 5,6,7,8-tetrahydronaphthalene (1.45 g; 11.3 mmol) in dichloromethane (22.7 mL) cooled to 0° C. was added chlorosulfonic acid (0.9 mL; 13.5 mmol) fast dropwise. The reaction mixture was stirred overnight warming to room temperature gradually. The reaction mixture was used in the next reaction directly without purification.
