反応手順

A mixture of 2-((2-aminophenyl)amino)-5-methylthiophene-3-carbonitrile, prepared as described in the previous step, (22.9 g, 100 mmol) in isopropanol (150 mL) and aqueous hydrochloric acid (50 mL, 18%) was heated at 80° C. for 3 hrs. The resulting suspension was filtered and the filter cake was dried to give the title compound as a red solid. 1H NMR (400 MHz CDCl3) δ 7.14-7.12 (t, 1H), 7.7.12-7.10 (t, 1H), 6.95-6.93 (d, J=8 MHz, 1H), 6.81-6.79 (d, J=8 MHz, 1H), 6.70 (s, 1H), 2.30 (s, 3H).
