Reaction Steps

Following the procedure as described in EXAMPLE 7.3 and making non-critical variations using 2,3-dihydrospiro[furo[2,3-g][1,4]benzodioxine-8,3′-indol]-2′(1′H)-one to replace (S)-2,3-dihydrospiro[furo[2,3-g][1,4]benzodioxine-8,3′-indol]-2′(1′H)-one, and 1-bromo-3-methoxypropane to replace 1-bromopentane, 1′-(3-methoxypropyl)-2,3-dihydrospiro[furo[2,3-g][1,3]benzodioxine-8,3′-indol]-2′(1′H)-one was obtained (71%) as a colorless solid: 1H NMR (300 MHz, CDCl3) δ 7.30-6.93 (m, 4H), 6.46 (s, 1H), 6.18 (s, 1H), 4.72 (ABq, 2H), 4.19-4.04 (m, 4H), 3.94-3.72 (m, 2H), 3.41 (t, J=5.9 Hz, 2H), 3.30 (s, 3H), 2.01-1.91 (m, 2H); 13C NMR (75 MHz, CDCl3) δ177.3, 155.2, 144.5, 142.5, 138.2, 132.4, 128.8, 123.8, 123.1, 121.1, 111.4, 108.5, 99.3, 80.0, 69.7, 64.5, 63.9, 58.7, 57.9, 37.6, 27.8; MS (ES+) m/z 367.9 (M+1).
