Procedure

A mixture of 1-methyl-4-prop-2-ynyl-piperazine (0.033 mL, 0.33 mmol), 5-bromo-7-methyl-2-(4-phenoxy-benzyl)-2,3-dihydro-isoindol-1-one (0.102 g, 0.25 mmol), PdCl2(PPh3)2 (0.011 g, 0.015 mmol), and CuI (0.0028 g, 0.015 mmol) in diisopropyl amine (4 mL) was stirred at 100° C. for 2 h. Workup and silica gel column chromatography using 10:1 CHCl3-MeOH afforded 7-methyl-5-[3-(4-methyl-piperazin-1-yl)-prop-1-ynyl)-2-(4-phenoxy-benzyl)-2,3-dihydro-isoindol-1-one (0.05 g, 43%).
