実験手順

3-benzyl-5-(3-fluoro-4-hydroxyphenyl)-2-(4-fluorophenylamino)pyrimidin-4(3H)-one (731.4 mg, 1.804 mmol) and 4-chloropyridin-2-amine (473.7 mg, 3.685 mmol) were dissolved in NMP (8.0 ml) and Et3N (1.25 ml, 8.97 mmol) was added. The flask was fitted with a reflux condenser and placed in a preheated oil bath (190 C) and stirred under nitrogen. After 19 hours, more 4-chloropyridin-2-amine (409 mg, 3.20 mmol), DMAP (286.5 mg, 2.345 mmol), Et3N (0.50 ml, 3.6 mmol) were added, followed by NMP (1.0 ml). Stirring was continued at 190 C. After 23 hours, the reaction was cooled to room temperature, diluted with DCM, and washed with water (2×50 ml). The aqueous extracts were combined and extracted with DCM. Some MeOH (˜10%) was also used to help solubilize the biphasic mixture. All the organic extracts were combined, dried over sodium sulfate, filtered, concentrated, and purified on silica gel (˜3 inches, DCM->50:1->20:1 DCM/MeOH) to afford the desired 5-(4-(2-aminopyridin-4-yloxy)-3-fluorophenyl)-3-benzyl-2-(4-fluorophenylamino)pyrimidin-4(3H)-one, which was taken on to the next step. MS (ESI pos. ion) m/z: 498 (MH+). Calc'd exact mass for C28H21F2N5O2: 497.
