Reaction Steps

Pd/C (7.67 mg, 0.0720 mmol) was added to a solution of 4-methoxy-2-methyl-7-nitro-2,3-dihydro-1H-isoindol-1-one in MeOH (2 mL) and EtOAc (2 mL) and the mixture was hydrogenated at stp overnight. The solution was filtered and the title compound was not further purified. MS (ES+): m/z 193.14 (100) [MH+]; HPLC: tR=0.65 min (UPLC, analytical).
