Reaction Steps

A mixture of 2,3-dihydro-isoindol-1-one (0.133 g, 1 mmol), 1-bromomethyl-2,4-difluoro-benzene (0.248 g, 1.2 mmol), Cs2CO3 (0.816 g, 2.5 mmol), and 18-crown-6 (0.026 g, 0.11 mmol) in acetone (5 mL) was stirred at 70° C. for 16 h. Workup and silica gel column chromatography using 30% ethyl acetate in hexane afforded 2-(2,4-difluoro-benzyl)-2,3-dihydro-isoindol-1-one (0.199 g, 77%). 1H NMR (300 MHz, CDCl3): δ (ppm) 4.34 (s, 2H), 4.84 (s, 2H), 6.85 (m, 2H), 7.35-7.54 (m, 4H), 7.86 (d, 1H).
