実験手順

A mixture of 50 parts of 4-(butylamino)-3-nitrobenzoic acid and 240 parts of methanol was hydrogenated in a Parr apparatus at 3.105Pa and at room temperature with 40 parts of Raney Nickel catalyst under nitrogen atmosphere. After the calculated amount of hydrogen was taken up, the catalyst was filtered off over diatomaceous earth and the filtrate was evaporated to dry, yielding 43.7 parts (100%) of 3-amino-4-(butylamino)benzoic acid; mp. 158° C. (int. 8).
