Reaktionsschritte

6-Bromo-4-chloro-7H-pyrrolo[2,3-d]pyrimidine (100 mg, 0.41 mmol), prepared as in reference 1, is mixed with resorcinol (451 mg, 4.1 mmol) and diisopropylethylamine (714 μL, 4.1 mmol) in dioxane (1.3 mL). The mixture is heated to 150° C. for 3 days, with stirring. The reaction is then cooled to ambient temperature and the solvent is removed. The resultant crude product is purified by flash column chromatography using a gradient of 3-5% MeOH in DCM to yield 5-(6-bromo-7H-pyrrolo[2,3-d]pyrimidin-4-yloxyl)-phenol (41 mg; 32%).
