Reaction Steps

A solution of 6-benzyloxy-3-chloromethyl-2-isobutyl-4-phenyl-1(2H)-isoquinolinone (2.59 g, 6 mmol) and potassium phthalimide (1.67 g, 9 mmol) in N,N-dimethylformamide (30 mL) was stirred at room temperature for 6 h. The reaction mixture was poured into water and extracted with ethyl acetate. After washing the extract with water, the extract was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The obtained crystals were recrystallized from ethyl acetate-diisopropyl ether to give 2-[(6-benzyloxy-2-isobutyl-1-oxo-4-phenyl-1,2-dihydro-3-isoquinolinyl)methyl]-1H-isoindole-1,3(2H)-dione (3.04 g, 93.5%) as crystals.
