Procedure

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-methoxyaniline (170 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-methoxy-phenol (96 mg; 66%); 1H NMR (500 MHz, d-methanol) δ 8.17 (s, 1H), 7.16 (s, 1H), 6.98 (d, J=8.6 Hz, 1H), 6.92 (d, J=8.6 Hz, 1H), 6.61 (s, 1H), 3.87 (s, 3H), 3.75 (s, 3H); LC-ESMS observed [M+H]+ 349.0 (calculated for C14H13BrN4O2, 348.0).
