Procedure

Following the procedure as described in EXAMPLE 12 and making non-critical variations using 2-fluoroaniline 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-fluorophenyl)-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 (57%) as a colorless solid: mp 195-197° C.; 1H NMR (300 MHz, DMSO-d6) δ10.37 (s, 1H), 7.75-7.59 (m, 2H), 7.51-7.35 (m, 2H), 7.34-7.11 (m, 6H), 7.00 (dd, J=7.4, 7.4 Hz, 1H), 6.87 (d, J=7.8 Hz, 1H), 6.52 (s, 1H), 6.40 (s, 1H), 5.19-5.00 (m, 2H), 4.85 (d, J=9.4 Hz, 1H), 4.70 (d, J=9.4 Hz, 1H), 4.47 (t, J=8.8 Hz, 2H), 2.93 (t, J=8.8 Hz, 2H); 13C NMR (75 MHz, DMSO-d6) δ177.8, 161.6, 161.2, 142.8, 135.8, 134.6, 132.7, 131.1, 129.1, 128.6, 127.8, 127.4, 127.3, 127.0, 126.0, 125.8, 124.8, 124.7, 124.2, 123.6, 120.9, 120.4, 119.6, 116.4, 116.2, 109.7, 92.9, 80.5, 72.6, 57.5, 41.4, 28.8; MS (ES+) m/z 529.2 (M+23).
