Procedure

To a solution of (2RS, 3RS)-4-nitro-benzoic acid 2-hydroxy-3-indol-1-yl-3-phenyl-propyl ester and triethylamine (1.4 mL, 10.5 mmol) in dichloromethane (20 mL) was added methanesulfonyl chloride (0.59 mL, 7.6 mmol) dropwise at 0-5° C. with stirring. After stirring for 30 minutes, the mixture was washed with a 1N aqueous solution of hydrochloric acid, 5% aqueous sodium bicarbonate, and water, dried over anhydrous sodium sulfate, filtered, and concentrated to give a light yellow fluffy solid. The crude product was recrystallized from dichloromethane with a minimum amount of diethyl ether to give (2RS,3RS)-4-nitro-benzoic acid-3-indol-1-yl-2-methanesulfonyloxy-3-phenyl-propyl ester as a yellow solid. MS (ESI) m/z 495 ([M+H]+).
