Reaction Steps

5,6-dimethyl-2-(3-fluorophenyl)-3-carboxymethyl-isoindolin-1-one [IUPAC name: 2-[2-(4-fluorophenyl)-5,6-dimethyl-3-oxo-2,3-dihydro-1H-isoindol-1-yl]acetic acid] (0.50 g, 1.6 mmol), 1-methylpiperazine (0.16 g, 1.6 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.31 g, 1.6 mmol) and 1-hydroxybenzotriazole hydrate (0.25 g, 1.6 mmol) were stirred in tetrahydrofuran (40 ml) at 25° C. for 16 hrs. The reaction solution was concentrated under reduced pressure, and the residue was purified by silica gel chromatography (chloroform:methanol=20:1) to give 0.56 g of the title compound.
