Procedure
Following the procedure as described in EXAMPLE 4 and making non-critical variations using 2-(chloromethyl)-3-(trifluoromethyl)pyridine hydrochloride to replace 2-(bromomethyl)tetrahydro-2H-pyran, and 5′-methyl-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, (5′-methyl-1′-{[3-(trifluoromethyl)pyridin-2-yl]methyl}-2,3-dihydrospiro[furo[2,3-g][1,4]benzodioxine-8,3′-indol]-2′(1′H)-one was obtained (62%) as a colorless solid: mp 137-139° C.
