反応手順
2.7 g of 10 percent palladium/carbon are added to a solution of 20.0 g (0.108 mol) of 6-fluoro-nitrobenzoic acid in a mixture of 200 ml of methanol and 27 ml of concentrated hydrochloric acid and the resulting mixture is hydrogenated at 35°-40° C. under a slight over-pressure. After filtration of the catalyst and concentration of the filtrate, the crude product is recrystallised from methanol/ether. There is obtained 6-fluoroanthranilic acid hydrochloride of melting point 176°-178° C. (decomposition).
