Reaction Steps

Following the procedure as described in EXAMPLE 5 and making non-critical variations using 6-(2-methoxyethoxy)spiro[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 2-(bromomethyl)pyridine hydrobromide to replace 5-(chloromethyl)-2-methoxypyrimidine, 6-(2-methoxyethoxy)-1′-(pyridin-2-ylmethyl)spiro[1-benzofuran-3,3′-indol]-2′(1′H)-one was obtained (72%): mp 94-95° C.; 1H NMR (300 MHz, CDCl3) δ8.56 (d, J=4.7 Hz, 1H), 7.69-7.59 (m, 1H), 7.25-7.09 (m, 4H), 7.05-6.95 (m, 1H), 6.92-6.82 (m, 2H), 6.81-6.73 (m, 1H), 6.37 (s, 1H), 5.08 (ABq, 2H), 4.83 (ABq, 2H), 3.93 (t, J=4.7 Hz, 2H), 3.62 (t, J=4.7 Hz, 2H), 3.36 (s, 3H); 13C NMR (75 MHz, CDCl3 δ 177.2, 155.5, 155.1, 153.7, 149.5, 142.1, 137.1, 132.0, 129.6, 128.9, 123.8, 123.5, 122.8, 121.6, 115.8, 110.5, 110.4, 109.5, 79.8, 71.0, 68.1, 59.1, 58.5, 46.1; MS (ES+) m/z 403.0 (M+1).
