실험 절차

4-(4-Benzyloxy-phenoxy)-2-chloro-pyrimidine (Step A, 2.03 g, 6.49 mmol) was dissolved in 10 mL DMSO in a sealed tube at 0° C. 2 N CH3NH2 (in THF) was added (4.9 mL, 9.7 mmol), and the tube was sealed, warmed first to RT for 2 h, then to 70° C. for 2 h with stirring. The reaction was cooled to RT and concentrated in vacuo to a DMSO solution. The crude solution was diluted into Et2O and 1 N NaOH (aq) was added. The layers were separated, and the organic layer was washed several times with water then brine. The organic layer was dried over Na2SO4, filtered, and concentrated in vacuo. The crude material was purified by silica gel column chromatography using a hexanes/EtOAc gradient to yield the title compound as a white solid. MS (MH+)=308.3; Calc'd 307.36 for C18H17N3O2.
