Participants

Reaction Steps

Following the procedure as described in EXAMPLE 12 and making non-critical variations using 2-fluoro-5-methylaniline to replace cyclohexanemethylamine, and 2-[(2′-oxo-5,6-dihydrospiro[benzo[1,2-b:5,4-b′]difuran-3,3′-indol]-1′(2′H)-yl)methyl]benzoic acid to replace 3-[(2′-oxo-5,6-dihydrospiro[benzo[1,2-b:5,4-b′]difuran-3,3′-indol]-1′(2′H)-yl)methyl]benzoic acid, N-(2-fluoro-5-methylphenyl)-2-[(2′-oxo-5,6-dihydrospiro[benzo[1,2-b:5,4-b′]difuran-3,3′-indol]-1′(2′H)-yl)methyl]benzamide was obtained (77%) as a colorless solid: mp 214-216° C.; 1H NMR (300 MHz, CDCl3) δ 8.25-8.06 (m, 2H), 7.65-7.57 (m, 1H), 7.47-7.33 (m, 2H), 7.33-7.26 (m, 1H), 7.22-7.12 (m, 2H), 7.07-6.86 (m, 4H), 6.46 (s, 1H), 6.40 (s, 1H), 5.27 (s, 2H), 4.95 (d, J=9.0 Hz, 1H), 4.68 (d, J=9.0 Hz, 1H), 4.52 (t, J=8.7 Hz, 2H), 2.96 (t, J=8.5 Hz, 2H), 2.36 (s, 3H); MS (ES+) m/z 543.1 (M+23).
