실험 절차

A solution of the product from Example 8F, 1-{[(1S,2S)-2-(4-bromophenyl)cyclopropyl]methyl}-(2S)-2-methylpyrrolidine (100 mg, 0.340 mmol), pyridazin-3(2H)-one (52.3 mg, 0.544 mmol), N1,N2-dimethylethane-1,2-diamine (0.088 mL, 0.816 mmol) and copper(I) iodide (78 mg, 0.408 mmol) in pyridine (2 mL) under a nitrogen atmosphere in a sealed vial was heated in an oil bath to 135° C. for 16 hours. The reaction mixture was cooled and diluted with DCM (10 mL), filtered through diatomaceous earth and washed with DCM. The filtrate was washed sequentially with H2O, 28-30% NH4OH (10 mL×2), and H2O, dried with MgSO4 and concentrated under reduced pressure. The residue was chromatographed on silica gel eluting with concentrated concentrated NH4OH/MeOH/DCM (0.4/4/96) to provide the title compound. 1H NMR (300 MHz, CD3OD) δ 0.90-0.97 (m, 1H), 1.03-1.09 (m, 1H), 1.15 (d, J=6 Hz, 3H), 1.23-1.33 (m, 1H), 1.39-1.49 (m, 1H), 1.70-1.80 (m, 2H), 1.82-2.05 (m, 3H), 2.26-2.42 (m, 2H), 3.16 (dd, J=12 Hz, J=6 Hz, 1H), 3.21-3.28 (m, 1H), 7.07 (d, J=6 Hz, 2H), 7.21 (dd, J=6 Hz, J=1.5 Hz, 2H), 7.43 (d, J=6 Hz, 2H), 7.47 (dd, J=9 Hz, J=3 Hz, 1H), 8.02 (dd, J=6 Hz, J=1.5 Hz, 1H).
