Versuchsvorschrift
The material was prepared by the catalytic reduction of 2-methoxy-6-nitroaniline to 3-methoxybenzene-1,2-diamine using a hydrogen atmosphere at 40 psi and 10% palladium on carbon (50% w/w water) in methanol. The resulting crude diamine was subsequently reacted with cyanogen bromide in an acetonitrile-water mixture according to previous procedure and used without further purification. 1H-NMR (400 MHz, CDCl3), δ 12.40 (bs, 1H), 7.26 (d, 1H), 7.15 (t, 1H), 6.77 (d, 1H), 6.59 (bs, 2H), 3.73 (s, 3H). MS (EI): 164 (MH+).
