This compound has unique chemical properties. The synthetic route is as follows. Formula: C9H7N3O
4-Chloro-2-pvridin-2-vl-pyrimidine; 2-Pyridin-2-yl-3H-pyrimidin-4-one, (0.945g, 5.45 mmol) was stirred in dichloromethane (25 mL) and phosphorous oxychloride (10 mL, 107 mmol) at 80C for 1 h. The phosphorous oxychloride and dichloromethane was removed by vacuo. Crushed ice (50 mL) was added to the reaction mixture followed by K2CO3 (1 M, aq. ) until pH reached 7. The resulting mixture was extracted with ethyl acetate (3×50 mL). The combined organic layers were extracted with brine (1×30 mL) and dried (MgS04). The solvent was evaporated to give the title compound (0.975 g, 93%). ‘H NMR (400 MHz, dmso-d6) 8 7.6 (t, J=5. 5 Hz, 1 H) 7.8 (d, J=5. 1 Hz, 1 H) 8.0 (td, J=7. 8,1. 2 Hz, 1 H) 8.4 (d,. J=7. 7 Hz, 1 H) 8.8 (m, 1 H) 8.9 (d, J=5. 0 Hz, 1 H).
