Procedure

To 3-[3-tert-butylsulfanyl-1-(4-chloro-benzyl)-5-isopropyl-1H-indol-2-yl]-2,2-dimethyl-propionic acid (prepared according to the procedures described in U.S. Pat. No. 5,081,138 issued Jan. 14, 1992; 0.25 g, 0.53 mmol) suspended in CH2Cl2 (5 mL) was added oxalyl chloride (48 uL, 0.56 mmol) and catalytic DMF. The reaction was stirred at room temperature for 3 hours, and then concentrated to give I-1, which was used without further purification.
