Versuchsvorschrift

A solution of 3-nitro-5-carboxyphenylboronic acid (3.3 g, 0.016 mol) in absolute ethanol (25 ml) was hydrogenated in the presence of Raney Nickel (1 g) at 50 lbs per square inch for 4 hours in a Parr shaker. The catalyst was removed by filtration and the solvent was removed on a rotary evaporator. The solid obtained was recrystallized from water. M.P. 210°-12° C.
