Isopropyl iodide → 5-Iodo-7-isopropyl-7H-pyrrolo[2,3-d]pyrimidine

Participants

Reaction Steps

To a mixture of 5-iodo-7H-pyrrolo[2,3-d]pyrimidine (Preparation 201, 2.90 g, 12.0 mmol) and cesium carbonate (5.78 g, 17.8 mmol) in DMF (45 mL) was added 2-iodopropane (1.78 mL, 17.8 mmol). The mixture was stirred at room temperature for 3 hours. The reaction mixture was then poured onto saturated aqueous ammonium chloride (500 mL) and a solid precipitated. The solid was collected by filtration, rinsed with water (200 mL) and dried under reduced pressure for 17 hours to afford the title compound as a brown solid in 77% yield, 2.61 g.
