実験手順
To a solution (200 mL) of m-amino benzoic acid (200 g, 1.46 mol) in concentrated HCl was added an aqueous solution (250 mL) of NaNO2 (102 g, 1.46 mol) at 0° C. The reaction mixture was stirred for 1 h and a solution of SnCl2.2H2O (662 g, 2.92 mol) in concentrated HCl (2 L) was then added at 0° C., and the reaction stirred for an additional 2 h at RT. The precipitate was filtered and washed with ethanol and ether to yield 3-hydrazino-benzoic acid hydrochloride as a white solid.
