Participants

Reaction Steps

A mixture of 5-bromo-2-(4-phenoxy-benzyl)-2,3-dihydro-isoindol-1-one (0.039 g, 0.1 mmol), 1-methyl piperazine (0.022 mL, 0.2 mmol), Pd2.dba3 (0.009 g, 0.01 mmol), BINAP (0.012 g, 0.02 mmol), and sodium tertiary-butoxide (0.030 g, 0.3 mmol) in toluene (3 mL) was heated to reflux for 3 h. Workup and silica gel column chromatography using 30% ethyl acetate in hexane afforded 5-(4-Methyl-piperazin-1-yl)-2-(4-phenoxy-benzyl)-2,3-dihydro-isoindol-1-one (0.017 g, 41%). 1H NMR (300 MHz, CDCl3): δ (ppm) 2.37 (s, 3H), 2.58 (m, 4H), 3.32 (m, 4H), 4.20 (s, 2H), 4.72 (s, 2H), 6.83-7.36 (m, 11H), 7.75 (d, 1H).
