반응 단계
5-(6-bromo-7H-pyrrolo[2,3-d]pyrimidin-4-yloxyl)-phenol (14 mg, 0.0448 mmol) is mixed with 3-amninophenylboronic acid (13 mg, 0.0896 mmol), Pd(dppf)Cl2.CH2.Cl2 (7.5 mg, 0.009 mmol), and K3PO4 (19 mg, 0.0896 mmol) in anhydrous dioxane (0.8 mL) under an argon atmosphere. The mixture is heated to 80° C. for 18 hours, with stirring. The reaction is then cooled to ambient temperature and filtered through a pad of silica with 10% MeOH in DCM. The filtrate is concentrated and the resulting crude product is purified by reverse phase HPLC using a C18 column and 0-95% acetonitrile/water gradient to give 3-[6-(3-amino-phenyl)-7H-pyrrolo[2,3-d]pyrimidin-4-yloxy]-phenol (7.1 mg, 50%); 1H NMR (500 MHz, DMSO): δ 8.27 (s, 1H), 7.29 (t, J=8.1 Hz, 1H), 7.20 (t, J=7.9 Hz, 1H), 7.10-7.17 (m, 2H), 6.68-7.08 (m, 4H), 6.52 (s, 1H); LC-ESMS observed [M+H]+ 319.1 (calculated for C18H14N4O2, 318.11).
