Using an adaptation of the method described in Procedure 9, substituting 1-[3-(3-bromoxanthen-9-ylidene)-8-aza-bicyclo[3.2.1]oct-8-yl]-2,2,2-trifluoro-ethanone, 1j for 9-(8-aza-bicyclo[3.2.1]oct-3-ylidene)-9H-xanthene-3-carboxylic acid diethylamide, 8a, the title compound 1-[3-(3-bromo-9H-xanthen-9-yl)-8-aza-bicyclo[3.2.1]oct-8-yl]-2,2,2-trifluoro-ethanone, 2j was obtained after puirification via flash column chromatography (eluent gradient: 5% to 25% EtOAc in heptane). MS m/z (MH+) 465.8.
