Procedure
Following the procedure as described in EXAMPLE 12 and making non-critical variations using 3-chlorobenzylamine 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-chlorobenzyl)-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 (84%) as a colorless solid: 1H NMR (300 MHz, CDCl3) δ 7.52-7.47 (m, 1H), 7.39-7.15 (m, 9H), 7.09-7.00 (m, 3H), 6.44 (s, 1H), 6.40 (s, 1H), 5.21-5.06 (m, 2H), 4.93 (d, J=9.0 Hz, 1H), 4.69 (d, J=9.0 Hz, 1H), 4.62 (d, J=5.9 Hz, 2H), 4.52 (t, J=8.6 Hz, 2H), 2.95 (t, J=8.6 Hz, 2H); MS (ES+) m/z 559.1 (M+23).
