6-Bromo-4-chloro-7H-pyrrolo[2,3-d]pyrimidine (100 mg, 0.41 mmol), prepared as in reference 1, is mixed with 3-hydroxy-4-methylaniline (150 mg, 1.22 mmol) and diisopropylethylamine (213 μL, 1.22 mmol) in n-butanol (1.3 mL). The mixture is heated to 120° C. for 18 hours, 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-ylamino)-2-methyl-phenol (92 mg; 70%).
