Participants

Reaction Steps

To a solution of 3,4-diaminobenzoic acid methyl ester (3.32 g, 20 mmol) and 2,6-dichlorobenzaldehyde (3.5 g, 20 mmol) in DMF (20 mL)+water (2 mL) was added oxone (2.46 g, 4 mmol). The mixture was stirred at RT for 18 h then EtOAc was added. The mixture was washed with water and brine then was dried over sodium sulfate. The solvent was removed under reduced pressure to give the title compound as a yellow solid.
