Reaction Steps

Following the procedure described in EXAMPLE 10.21, and making non-critical variations using spiro[furo[2,3-f][1,3]benzodioxole-7,3′-indol]-2′(1′H)one to replace 5,5-dimethyl-5,6-dihydrospiro[benzo[1,2-b:5,4-b′]difuran-3,3′-indol]-2′(1′H)-one, and 1-(bromomethyl)-2-(trifluoromethoxy)benzene to replace 2-(bromomethyl)-5-(trifluoromethyl)furan, the title compound was obtained (77%) as a white solid: mp 130-135° C.; MS (ES+) m/z 456.3 (M+1).
