Reaction Steps

A mixture of 2-bromomethyl-6-iodo-benzoic acid methyl ester (0.200 g, 0.56 mmol), 4-chloro-benzylamine (0.7 mmol), and K2CO3 (0.166 g, 1.2 mmol) in toluene (5 mL) was heated with stirring at 100° C. for 2 h. Workup and silica gel column chromatography using 30% ethyl acetate in hexane afforded 2-(4-chloro-benzyl)-7-iodo-2,3-dihydro-isoindol-1-one (0.084 g, 39%). 1H NMR (300 MHz, CDCl3): δ (ppm) 4.16 (s, 2H), 4.75 (s, 2H), 7.16-7.40 (m, 6H), 7.92 (d, 1H). GC-MS: m/z 367 (M)+.
