Reaction Steps

To a solution of (S)-1-(4-chlorophenyl)-5-(3-hydroxyphenyl)imidazolidin-2-one (210 mg, 0.73 mmol, prepared by using a similar procedure as described in Example 460) and 3-chloropyradazine (167 mg, 1.46 mmol) in DMF (2 mL) is added Cs2CO3 (354 mg, 1.09 mmol). The mixture is stirred at 80° C. for 14 h and is then cooled to room temperature. The reaction mixture is then treated with water (20 mL) and extracted with EtOAc (3×15 ml). The combined organic layers are washed with brine and dried (MgSO4). After removing the drying agent, the solution is concentrated and purified by flash column chromatography (silica gel, 0%˜10% MeOH/CH2Cl2) to provide the title compound. 1H NMR (CDCl3, 400 MHz) δ 8.95 (dd, J=4.4, 1.2 Hz, 1H), 7.49 (dd, J=8.8, 4.4 Hz, 1H), 7.32-7.40 (m, 3H), 7.10-7.20 (m, 6H), 5.28 (dd, J=8.0, 4.8 Hz, 1H), 4.70 (br s, 1H), 3.97 (t, J=8.8 Hz, 1H), 3.41 (dd, J=8.8, 6.0 Hz, 1H); HPLC-MS calculated for C19H15ClN4O2 (M+H+) 367.1, found 367.1.
