Procedure
The potassium salt of 5-isopropyl-3-methylbenzofuran-2-sulfonic acid (100 mg, 0.34 mmol) was mixed with POCl3 (5 mL) and the reaction mixture was heated at 60° C. over night. The POCl3 was evaporated and the crude product was dissolved in CH2Cl2 and passed through a small amount of silica to give the title compound (30 mg, 33%).
