反応手順

To a suspension of 2-amino-4,5-dimethoxybenzamide (5.05 g, 25.7 mmole) and 3-nitro benzoyl chloride (5.2 g, 28.0 mmole) CHCl3 (120 ml) was added pyridine (50 ml) drop wise at RT. The reaction mixture was stirred at RT for 24 h. The solvent was removed in vacuo and residue was triturated with Et2O, filtered and dried under high vacuum to give 4,5-dimethoxy-2-(3-nitrophenyl)aminobenzamide, which was used directly in the next step.
