実験手順

To a suspension of 5-Amino-4-methyl-2-(1-methyl-piperidin-4-yl)-6-nitro-isoindole-1,3-dione (1.7 g, 5.34 mmol) and 10% Pd/C (250 mg) was added MeOH (100 mL) carefully and evacuated in vacuo. The flask was filled with hydrogen under balloon pressure and stirred for 1 h. The reaction mixture was filtered and evaporated in vacuo to afford the crude 5,6-diamino-4-methyl-2-(1-methyl-piperidin-4-yl)-isoindole-1,3-dione (1.5 g, quant.), which was used as such for further reaction.
