Reaction Steps

A mixture of 5-bromo-7-methyl-2-(4-trifluoromethoxy-benzyl)-2,3-dihydro-isoindol-1-one (0.120 g, 0.3 mmol), 2-(4-methyl-piperazin-1yl)-ethanol (0.074 mL, 0.6 mmol), Pd(OAc)2 (0.002 g, 0.006 mmol), and Cs2CO3 (0.195 g, 0.6 mmol) in toluene (3 mL) was stirred at 100° C. for 24 h. Workup and silica gel column chromatography using 5:1 CHCl3-MeOH afforded 7-methyl-5-[2-(4-methyl-piperazin-1-yl)-ethoxy]-2-(4-trifluoromethoxy-benzyl)-2,3-dihydro-isoindol-lone (0.025 g, 18%). 1H NMR (300 MHz, CDCl3): δ (ppm) 2.49 (bs, 8H), 2.75 (s, 3H), 2.83 (t, 2H), 4.16 (m, 5H), 4.73 (s, 2H), 6.70 (d, 2H), 7.13-7.37 (m, 4H).
