실험 절차

To a stirred solution of 2-[3-(tritylamino)phenyl]ethanol (5.00 g, 13.2 mmol) and triethylenediamine (2.22 g, 19.8 mmol) in DCM (52.7 mL) under nitrogen at 0° C. was added portion-wise p-nitrobenzenesulfonyl chloride (3.50 g, 15.8 mmol) over a period of 5 min. The resulting mixture stirred at 0° C. for 40 min and then saturated aqueous sodium bicarbonate solution (˜50 mL) was added. The mixture was stirred at room temperature for 10 min and then the layers were separated. The aqueous layer was extracted with DCM (2ט50 mL) and the combined organic layers were dried over sodium sulfate, filtered, and concentrated under reduced pressure to give the title compound (7.44 g, 100% yield) as an orange-yellow foamy solid.
