Procedure

A mixture of 2-bromomethyl-6-iodo-benzoic acid methyl ester (0.107 g, 0.3 mmol), 3-methoxy-benzylamine (0.052 mL, 0.4 mmol), and K2CO3 (0.138 g, 1.0 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 7-iodo-2-(3-methoxy-benzyl)-2,3-dihydro-isoindol-1-one (0.031 g, 27%). 1H NMR (300 MHz, CDCl3): δ (ppm) 3.78 (s, 3H), 4.16 (s, 2H), 4.74 (s, 2H), 6.79 (m, 3H), 7.14-7.38 (m, 3H), 7.91 (d, 1H). GC-MS: m/z 379 (M)+.
