실험 절차
A mixture of 7H-pyrrolo[2,3-d]pyrimidine (Preparation 202, 28.0 g, 235 mmol) and N-iodosuccinimide (55.4 g, 246 mmol) in acetonitrile (470 mL) was stirred at room temperature for 16 hours. The solids were filtered, rinsed with acetonitrile (150 mL) and dried in vacuo. The solid was dissolved in 1.5 L of 1N aqueous sodium hydroxide solution and to it was added 2N aqueous hydrogen chloride solution until ˜pH 9. The resulting precipitate was filtered, rinsed with water (300 mL), and dried in vacuo for 16 hours at 70° C., ˜10 mbar, to afford the title compound in 81% yield, 46.84 g.
