Procedure
Aq. 2.5M NaOH (3 mL) was added to a stirring mixture of 2-thiophenesulfonyl chloride (1.03 g, 5.61 mmol), 4-bromoindole (1.00 g, 5.10 mmol) and tetrabutylammonium hydrogen sulfate (87 mg, 0.05 mmol). The reaction was stirred over night (22 h). Additional 2-thiophenesulfonyl chloride (50 mg, 0.27 mmol) was added with continuous stirring for 3 h. The layers were allowed to separate. The organic layer was washed twice with water, dried and concentrated to get the title compound (1.67 g, 96%) as a gray solid.
