Chloroform methanol → 7-Chloro-5-[3-(4-methyl-piperazin-1-yl)-propyl]-2-(4-phenoxy-benzyl)-2,3-dihydro-isoindol-1-one

Participants

Reaction Steps

A mixture of 7-chloro-5-[3-(4-methyl-piperazin-1-yl)-prop-1-ynyl)-2-(4-phenoxy-benzyl)-2,3-dihydro-isoindol-1-one (0.073 g, 0.15 mmol) and 10% palladium-carbon (0.015 g) in ethanol (25 mL) was reduced under 45 p.s.i hydrogen. Workup and silica gel column chromatography using 5:1 CHCl3-MeOH afforded 7-chloro-5-[3-(4-methyl-piperazin-1-yl)-propyl]-2-(4-phenoxy-benzyl)-2,3-dihydro-isoindol-1-one (0.035 g, 50%). 1H NMR (300 MHz, CDCl3): δ (ppm) 1.79 (m, 2H), 2.22-2.60 (m, 13H), 2.66 (t, 2H), 4.22 (s, 2H), 4.74 (s, 2H), 6.86-7.38 (m, 11H).
