Steps:

101 3,4-diaminobenzonitrile

EXAMPLE 101 3,4-diaminobenzonitrile 3-Amino-4-nitrobenzonitrile (20.00 g, 0.042 mol) was hydrogenated under 50 psi of hydrogen gas in 250 mL of anhydrous ethanol with 1.00 g of 10% Pd/C for 5 hours. The mixture was then filtered through a pad of celite and the filtrate concentrated. Trituration of the resulting solid with diethyl ether afforded 11.40 g of the desired product as a tan solid (70%). ¹H NMR (CD₃OD): δ6.88 (m, 2H), 6.65 (d, 2H, J=8.53 Hz).
