A 3.00 M solution of magnesium chloride in THF (13.0 mL, 39.0 mmol) was added dropwise to a stirred solution of 4-chloro-1H-pyrrolo[2,3-d]pyrimidine (2.50 g, 16.3 mmol) and ferric acetylacetonate (700. mg 1.98 mmol) in THF (30.0 mL) under an atmosphere of argon. The resulting reaction mixture was stirred at rt for 8 h. The mixture was poured onto a mixture of ice (100 mL) and ammonium chloride (1.00 g) and the mixture was extracted with chloroform. Volatiles were removed in vacuo, and C-18 column chromatography eluting with a gradient of 0 to 60% AcCN in water with 0.1% AA afforded the title compound (1.50 g, 69%). LC/MS: Rt=0.94 min, ES+ 134 (AA standard).
