Reaction Steps

The product of Step A, methyl (3S,4R)-4-(4-chlorophenyl)pyrrolidine-3-carboxylate (0.46 g, 1.92 mmol) was dissolved in dioxane (2 ml). DIPEA (1.34 ml, 7.67 mmol) and 3-chloro-6-methylpyridazine (0.74 g, 5.76 mmol) were added. The reaction was conducted at 180° C. for 5 minutes with microwave. Then, the reaction mixture was concentrated in vacuo. EtOAc was added to the obtained residue. The mixture was diluted with EtOAc, washed with water and purified by column chromatography (eluent: EtOAc/Hex=1/2) to give the title compound (0.48 g, 75%).
