Reaction Steps

4-[1-(4-Benzyloxy-5-methoxy-2-nitro-phenyl)-2-(1,3-dioxo-1,3-dihydro-isoindol-2-yl)-ethylamino]-benzonitrile (2.7 g, 5 mmoles) was dissolved in ethanol (100 ml) and hydrazine hydrate (0.65 ml, 20 mmoles) added. The reaction was heated to 60° C. for 3 hours then at room temperature for 48 hours. The solids that precipitated were filtered off and the residue submitted to flash chromatography to yield 4-[2-Amino-1-(4-benzyloxy-5-methoxy-2-nitro-phenyl)-ethylamino]-benzonitrile (1.5 g). 1HNMR(CDCl3): 7.75 (s,1H), 7.3-7.5 (m, 7H), 7.05 (s,1H), 6.45 (d, 2H), 5.80 (bs, 1H), 5.32 (m, 1H), 5.19 (s, 2H), 3.81 (s, 3H), 3.25 (dd, 1H), 3.0 (dd, 1H), 1.65 (bs, 2H).
