Procedure

Following the procedure as described in EXAMPLE 4 and making non-critical variations using (R)-(2,3-dihydrospiro[furo[2,3-g][1,4]benzodioxine-8,3′-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)-5-(trifluoromethyl)furan to replace 2-(bromomethyl)tetrahydro-2H-pyran, (R)-1′-{[5-(trifluoromethyl)furan-2-yl]methyl}-2,3-dihydrospiro[furo[2,3-g][1,4]benzodioxine-8,3′-indol]-2′(1′H)-one was obtained (92%) as a colorless solid: mp 64-68° C.
