HCID 461948551'-{[3-(trifluoromethyl)pyridin-2-yl]methyl}-2,3-dihydrospiro[furo[2,3-g][1,3]benzodioxine-8,3'-indol]-2'(1'H)-one

Procedure

Following the procedure as described in EXAMPLE 7.3 and making non-critical variations using 2,3-dihydrospiro[furo[2,3-g][1,4]benzodioxine-8,3′-indol]-2′(1′H)-one to replace (S)-2,3-dihydrospiro[furo[2,3-g][1,4]benzodioxine-8,3′-indol]-2′(1H)-one, and 2-(chloromethyl)-3-(trifluoromethyl)pyridine hydrochloride to replace 1-bromopentane, 1′-{[3-(trifluoromethyl)pyridin-2-yl]methyl}-2,3-dihydrospiro[furo[2,3-g][1,3]benzodioxine-8,3′-indol]-2′(1′H)-one was obtained (40%) as a colorless solid: 1H NMR (300 MHz, CDCl3) δ 8.62 (d, J=4.7 Hz, 1H), 7.96 (d, J=7.9 Hz, 1H), 7.32-6.96 (m, 4H), 6.71-6.54 (m, 2H), 6.48 (s, 1H), 5.22-5.28 (m, 2H), 4.80-4.90 (m, 2H), 4.21-4.06 (m, 4H); 13C NMR (75 MHz, CDCl3) δ 178.1, 155.1, 152.3, 144.5, 142.3, 138.2, 134.3, 134.2, 134.1, 134.1, 132.7, 129.2, 128.6, 125.6, 124.9, 124.5, 124.1, 123.8, 123.6, 123.2, 122.1, 122.0, 121.6, 112.4, 108.5, 99.1, 80.0, 64.5, 63.9, 58.2, 42.2, 42.2; MS (ES+) m/z 454.8 (M+1).
