Reaction Conditions

Reaction Steps

A mixture of 2-bromomethyl-6-iodo-benzoic acid methyl ester (0.178 g, 0.5 mmol), 3-phenyl-butylamine (0.090 g, 0.6 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 7-iodo-2-(3-phenyl-butyl)-2,3-dihydro-isoindol-1-one (0.046 g, 23%). 1H NMR (300 MHz, CDCl3): δ (ppm) 1.32 (d, 3H), 1.96 (m, 2H), 2.78 (m, 1H), 3.54 (m, 2H) 4.16 (s, 2H), 7.14-7.38 (m, 7H), 7.88 (d, 1H). GC-MS: m/z 391 (M)+.
