Procedure

Following the procedure as described in EXAMPLE 12 and making non-critical variations using m-toluidine 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-(3-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 (81%) as a colorless solid: mp 229-231° C.; 1H NMR (300 MHz, CDCl3) δ8.85 (s, 1H), 7.64-7.55 (m, 2H), 7.49-7.42 (m, 1H), 7.40-7.33 (m, 2H), 7.32-7.16 (m, 4H), 7.11-7.03 (m, 2H), 6.96 (d, J=7.6 Hz, 1H), 6.40 (s, 2H), 5.22-5.05 (m, 2H), 4.93 (d, J=9.0 Hz, 1H), 4.67 (d, J=9.0 Hz, 1H), 4.52 (t, J=8.7 Hz, 2H), 2.96 (t, J=8.5 Hz, 2H), 2.35 (s, 3H); MS (ES+) m/z 525.11 (M+23).
