The product of Example 49B (30 mg, 0.105 mmole), 3,6-dichloropyridazine (18.8 mg, 0.126 mmole), and triethylamine (45 ml, 0.036 mmole) were dissolved in 1 ml of acetonitrile and heated at 60° C. under N2 for 24 hours. The mixture was cooled to room temperature, quenched with water and extracted with dichloromethane (5×). The combined organics were dried over sodium sulfate, filtered and concentrated under reduced pressure and purified by chromatography (eluting with a mixture of 0.5% ammonium hydroxide and 5% methanol in dichloromethane) to provide the title compound. 1H NMR (300 MHz, CDCl3) δ ppm 7.24 (s, 1H) 7.21 (s, 1H) 6.91-6.96 (m, 2H) 6.53-6.58 (m, 2H) 4.13-4.21 (m, 1H) 3.72-3.83 (m, 4H) 3.50-3.61 (m, 1H) 3.36-3.45 (m, 1H) 3.11-3.19 (m, 4H) 2.99-3.08 (m, 1H) 2.60-2.80 (m, 4H) 2.46 (s, 3H) 2.13-2.23 (m, 1H) 1.89-2.04 (m, 1H); MS, (M+H)+=399.
