Following the procedure as described in EXAMPLE 4 and making non-critical variations using 6-methoxyspiro[1-benzofuran-3,3′-indol]-2′(1′H)-one to replace 5,6-dihydrospiro[benzo[1,2-b:5,4-b′]difuran-3,3′-indol]-2″(1′H)-one, and (R)-(tetrahydrofuran-2-yl)methyl 4-methylbenzenesulfonate to replace 2-(bromomethyl)tetrahydro-2H-pyran, 6-methoxy-1′-[(2R)-tetrahydrofuran-2-ylmethyl]spiro[1-benzofuran-3,3′-indol]-2′(1′H)-one was obtained (54%) as a colorless liquid: 1H NMR (300 MHz, CDCl3) (diastereomers) δ 7.32-7.25 (m, 1H), 7.16-6.99 (m, 3H), 6.61 (d, J=8.1 Hz, 1H), 6.52 (d, J=2.1 Hz, 1H), 6.36 (dd, J=8.1, 2.1 Hz, 1H), 4.94 (d, J=9.0 Hz, 1H), 4.69 (d, J=9.0 Hz, 1H), 4.32-4.22 (m, 1H), 4.00-3.66 (m, 4H), 3.77 (s, 3H), 2.10-1.66 (m, 4H); 13C NMR (75 MHz, CDCl3) (diastereomers) δ178.0, 177.9, 162.0, 161.4, 142.9, 142.8, 132.4, 132.3, 128.7, 128.6, 123.6, 123.5 (2C), 123.4, 123.2, 121.0, 120.9, 109.6, 109.3, 107.4 (2C), 96.5, 80.5, 80.4, 76.8, 76.7, 68.2, 68.1, 57.5, 55.5, 44.5 (2C), 29.2, 28.9, 25.6, 25.5; MS (ES+) m/z 352.1 (M+1).
