Reaction Steps

To a solution of Compound 2 (70 mg, 0.26 mmol) in DMF (1.4 mL), triethylamine (91 μL, 0.68 mmol) and 2-bromomethyl-3-nitrobenzoic acid methyl ester (79 mg, 0.29 mmol) were added, followed by stirring at 80° C. for 7.0 hours under nitrogen atomosphere. The reaction mixture was added with water, extracted with ethyl acetate and the organic layer was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (chloroform to chloroform/methanol=90/10) to obtain (E)-2-{2-[2-(1H-indazol-3-yl)vinyl]phenyl}-4-nitro-2,3-dihydroisoindol-1-one (61 mg, 60%).
