실험 절차

The product of Example 1A (4.54 g, 12.6 mmole), 3(2H)-pyridazinone (2.41 g, 25.2 mmole), copper powder (1.60 g, 25.2 mmole) and potassium carbonate (5.21 g, 37.7 mmole) were dissolved in 63 ml of quinoline and heated at 150° C. under N2 for 48 hours. The mixture was cooled to room temperature, diluted with hexane (15 ml) and filtered through a CELITE filter (CELITE is a registered trademark of Johns-Manville Corporation of Denver, Colo.). The filtrate was concentrated under reduced pressure and the residue was purified by chromatography (eluting first with diethyl ether, followed by dichloromethane, then elution with a mixture of 5% MeOH in dichloromethane) to provide the title compound, 2-{4′-[(3aR,6aR)-5-methylhexahydropyrrolo [3,4-b]pyrrol-1(2H)-yl]-1,1′-biphenyl-4-yl}pyridazin-3(2H)-one. 1H NMR (300 MHz, CDCl3) δ ppm 7.91 (dd, J=3.73, 1.70 Hz, 1 H) 7.61-7.65 (m, 4 H) 7.51 (d, J=8.48 Hz, 2 H) 7.25 (dd, dd, J=9.40, 4.07 Hz, 1 H) 7.07 (dd, J=9.49, 1.70 Hz, 1 H) 6.64 (d, J=8.81 Hz, 2 H) 4.19-4.27 (m, 1 H) 3.54-3.64 (m, 1 H) 3.28-3.38 (m, 1 H) 3.00-3.11 (m, 1 H) 2.56-2.85 (m, 4 H) 2.40 (s, 3 H) 2.10-2.29 (m, 1 H) 1.89-2.05 (m, J=6.78 Hz, 1 H); MS (M+H)+=373. The solid (3aR,6aR)-2-[4′-(5-methyl-hexahydro-pyrrolo [3,4-b]pyrrol-1-yl)-biphenyl-4-yl]-2H-pyridazin-3-one obtained showed a melting range of 204-207° C. (dec.).
