Following the procedure described in EXAMPLE 16.19 and making non-critical variations using 4′-bromo-1′-pentyl-2,3-dihydrospiro[furo[2,3-g][1,4]benzodioxine-8,3′-indol]-2′(1′H)-one to replace 4′-bromo-1′-methyl-2,3-dihydrospiro[furo[2,3-g][1,4]benzodioxine-8,3′-indol]-2′(1′H)-one, 4′-amino-1′-pentyl-2,3-dihydrospiro[furo[2,3-g][1,4]benzodioxine-8,3′-indol]-2′(1′H)-one was obtained (79%) as an orange solid: 1H NMR (300 MHz, CDCl3) δ 7.11-7.05 (m, 1H), 6.48 (s, 1H), 6.36-6.32 (m, 3H), 4.78 (s, 2H), 4.21-4.11 (m, 4H), 3.84-3.58 (m, 2H), 1.76-1.66 (m, 2H), 1.39-1.33, (m, 4H), 0.91 (t, J=6.6 Hz, 3H); MS (ES+) m/z 380.9 (M+1).
