反応手順

The title compound was prepared according to the procedure described in Example-3 using 5-(2-chloro-6-fluorophenyl)-2-(4-ethynylphenyl)-2,4-dihydro-3H-1,2,4-triazol-3-one (Intermediate-2, 0.100 g, 0.319 mmol), 4-(5-iodopyridin-2-yl)morpholine (Intermediate-6, 0.139 g, 0.470 mmol), TBAF (0.201 g, 0.638 mmol), bis(triphenylphosphine)palladium(II) chloride (0.020 g, 0.028 mmol) and DMSO (3.0 mL). The obtained product was purified with column chromatography on silica gel eluting with 2.0% MeOH:DCM to afford 0.020 g of the desired product. 1H NMR (300 MHz, DMSO d6): δ 3.58-3.61 (m, 4H), 3.82-3.85 (br s, 4H), 6.64 (d, J=8.7 Hz, 1H), 7.19 (t, 0.1=8.7 Hz, 1H), 7.36-7.47 (m, 2H), 7.58 (d, J=8.4 Hz, 2H), 7.63-7.67 (m, 1H), 8.03 (d, J=9.0 Hz, 2H), 8.38 (s, 1H), 10.14 (br s, 1H); MS (m/z): 473.64 (M−H)−.
