実験手順

A mixture of 4′-fluoro-2,3-dihydrospiro[furo[2,3-g][1,4]benzodioxine-8,3′-indol]-2′(1′H)-one (0.31 g, 1.00 mmol), 2-(chloromethyl)-3-(trifluoromethyl)pyridine hydrochloride (0.29 g, 1.50 mmol) and cesium carbonate (0.98 g, 3.00 mmol) in N,N′ dimethylformamide (10 mL) was heated at 60° C. for 2 h and was filtered while hot. The filtrate was allowed to cool to ambient temperature and water was added, causing a precipitate to be deposited. The solid was collected by filtration, washed with water (50 mL) and dried under vacuum. The residue was recrystallized from N,N′ dimethylformamide/water to afford 4′-fluoro-1′-{[3-(trifluoromethyl)pyridin-2-yl]methyl}-2,3-dihydrospiro[furo[2,3-g][1,4]benzodioxine-8,3′-indol]-2′(1′H)-one (0.39 g, 82%) as a beige solid: mp 245-247° C.; 1H NMR (300 MHz, DMSO-d6) δ 8.68 (d, J=4.5 Hz, 1H), 8.27 (d, J=7.65 Hz, 1H), 7.59 (dd, J=7.8, 4.9 Hz, 1H), 7.30 (ddd, J=8.2, 8.2, 5.8 Hz, 1H), 6.86 (d, J=9.0 Hz, 1H), 6.82 (d, J=7.8 Hz, 1H), 6.54 (s, 1H), 6.49 (s, 1H), 5.25 (ABq, J=17.4 Hz, 2H), 4.79 (q, J=9.4 Hz, 2H), 4.22-4.10 (m, 4H); 13C NMR (75 MHz, DMSO-d6) δ 176.5, 157.9 (d, 1JC-F=247 Hz), 154.6, 152.3, 152.1 (d, 5JC-F=1.2 Hz), 144.9 (d, 4JC-F=8.9 Hz), 144.3, 137.6, 135.1 (q, 4JC-F=4.9 Hz), 130.8 (d, 4JC-F=8.6 Hz), 125.6 (q, 1JC-F=274 Hz), 123.0, 122.9 (d, 2JC-F=32.3 Hz), 119.4, 117.1 (d, 3JC-F=19.3 Hz), 111.5, 109.9 (d, 3JC-F=19.9 Hz), 105.7 (d, 5JC-F=2.9 Hz), 98.4, 77.4, 64.1, 63.5, 56.0 (d, 5JC-F=1.7 Hz), 42.3 (q, 5JC-F=3.3 Hz); MS (ES+) m/z 460.9 (M+1).
