実験手順

To a stirred solution of 6-chloropyridazine-3-carboxylic acid (2-cyclopropylethyl)amide (0.020 g, 0.090 mmol) in dioxane (5 mL) was added 4-methyl-4-(2-trifluoromethylphenoxy)piperidine (0.015 g, 0.060 mmol), potassium carbonate (0.033 g, 0.240 mmol) and tetrabutyl ammonium bromide (0.002 g, 0.001 mmol). The resulting mixture was stirred at reflux for 48 hours, filtered and then concentrated in vacuo. The crude product was purified by column chromatography to yield the title compound in 20% yield (0.005 g). 1H NMR (300 MHz, CDCl3) δ 8.02-7.96 (m, 2H), 7.60-7.57 (m, 1H), 7.48-7.40 (m, 1H), 7.14-7.12 (d, J=8.0 Hz, 1H), 7.06-6.99 (m, 2H), 4.25-4.21 (m, 2H), 3.65-3.51 (m, 4H), 2.35-2.31 (m, 2H), 1.85-1.74 (m, 2H), 1.53-1.46 (dd, J=6.6 and 7.0 Hz, 2H), 1.20 (s, 3H), 0.77-0.69 (m, 1H), 0.48-0.42 (m, 2H), 0.11-0.05 (m, 2H). MS (ES+) m/z 449.4 (M+1).
