実験手順

Six grams (0.035 mole) of 4-amino-3-nitrobenzyl alcohol, 95 ml. of tetrahydrofuran and 0.5 g. of Raney Nickel were hydrogenated at 40 psi at room temperature until 3 moles of hydrogen were absorbed. The catalyst was filtered and the filtrate was evaporated in vacuo to yield 4.83 g. (82 percent yield) of 3,4-diaminobenzyl alcohol, mp 74°-75° C.
