A mixture of 4-trifluoromethyl-benzyl amine (0.142 mL, 1.0 mmol), 2-bromomethyl-4-fluoro-6-iodo-benzoic acid methyl ester (0.270 g, 0.73 mmol), and K2CO3 (0.207 g, 1.5 mmol) in toluene (4 mL) was heated with stirring at 100° C. for 2 h. The resulting mixture was filtered and concentrated. Silica gel column chromatography using 30% ethyl acetate in hexane afforded 5-fluoro-7-iodo-2-(4-trifluoromethyl-benzyl)-2,3-dihydro-isoindol-1-one (0.110 g, 35%). 1H NMR (300 MHz, CDCl3): δ (ppm) 4.18 (s, 2H), 4.84 (s, 2H), 7.10 (d, 1H), 7.42 (d, 2H), 7.60 (m, 2H), 7.66 (d, 1H). GC-MS: m/z 435 (M)+, 416 (M−19)+.
