Reaction Steps

Following the procedure as described in EXAMPLE 4 and making non-critical variations using 5-(chloromethyl)-4-(trifluoromethyl)thiazol-2-amine to replace 2-(bromomethyl)tetrahydro-2H-pyran, and spiro[furo[2,3-f][1,3]benzodioxole-7,3′-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, 1′-{[2-amino-4-(trifluoromethyl)-1,3-thiazol-5-yl]methyl}spiro[furo[2,3-f][1,3]benzodioxole-7,3′-indol]-2′(1′H)-one was obtained (4.0%) as a colorless solid: mp 165-167° C.; 1H NMR (300 MHz, DMSO-d6) δ7.39 (br, 2H), 7.32 (dd, J=7.7, 7.7 Hz, 1H), 7.18 (d, J=6.7 Hz, 1H), 7.05 (dd, J=7.5, 7.5 Hz, 1H), 6.98 (d, J=7.8 Hz, 1H), 6.69 (s, 1H), 6.12 (s, 1H), 5.91 (s, 2H), 5.02 (ABq, 2H), 4.70 (ABq, 2H); 13C NMR (75 MHz, DMSO-d6) δ176.8, 167.9, 155.9, 148.9, 142.2, 141.8, 134.7 (q, 1JCF=135 Hz), 132.1, 129.5, 124.5, 123.9, 123.8 (m), 119.9, 109.2, 103.2, 101.9, 93.9, 80.2, 57.8, 40.9; MS (ES+) m/z 462.1 (M+1).
