Reaction Steps

A toluene (1100 ml) solution of anthranilic acid (205.5 g) and formic acid (170 ml) was heated under reflux for 4.5 hours. After the solution was allowed to cool, hexane was added to crystals deposited. The crystals were collected by filtration and washed with hexane. The resulting crystals were dried at 110° C. under reduced pressure to obtain N-formyl-anthranilic acid (244.0 g, crude product) as white crystals.
