1-Fluoro-2-isocyanato-benzene (0.09 mL, 0.81 mmol) was added to a solution of (4-Amino-7-isopropyl-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-(2-amino-pyridin-4-yl)-methanone (0.20 g, 0.67 mmol) in pyridine (2 mL). The mixture was heated to 80° C. in a sealed tube for 2 h. The reaction mixture was quenched with water (10 mL) and extracted with hot EtOAc/MeOH (95:5, 3×10 mL). The combined organic extracts were dried (Na2SO4), filtered, and concentrated in vacuo. Purification by flash column chromatography (ethyl acetate/MeOH 99:1) afforded the title compound as a yellow solid (160 mg, 55%). MS: 434.2 (MH+); HPLC Rf: 5.83 min. (HPLC method 4); HPLC purity: 98%.
