Sodium Hydroxide → 4-(5-fluoro-2-methoxyphenyl)-6-iodo-7H-pyrrolo[2,3-d]pyrimidine

A solution of Example 3C (3.5 g, 6.78 mmol) in 70 mL dioxane was treated with aqueous sodium hydroxide (11.30 mL, 67.8 mmol, 6 M) and stirred at 100° C. for 1 hour. The reaction mixture was cooled and diluted with 300 mL of water. The aqueous mixture was extracted with ethyl acetate (3×), and the combined organic fractions were washed with brine, dried over magnesium sulfate and concentrated to give the title compound.
