반응 단계
4-(3-(4-(Trifluoromethyl)phenoxy)benzylidene)piperidine hydrochloride (200 mg, 0.541 mmol, from Example 53, Step 5), ethyl pyridazin-3-ylcarbamate (99 mg, 0.595 mmol) and triethylamine (0.15 mL, 1.08 mmol) were combined in acetonitrile (4.5 mL) and heated in a microwave at 180° C. for 40 min. The reaction mixture was cooled to RT and concentrated. The residue was purified by silica gel chromatography (50-100% EtOAc in CH2Cl2) to provide the title compound (156 mg).
