Reaction Steps

A solution of 5.3 g (0.0189 mol) of 2-amino-1-benzylideneamino-4-(4-fluorophenyl)-imidazole and 12.5 ml of hydrazine hydrate in 18.8 ml of diethylene glycol is stirred at 140° C. for 15 hours. After cooling to 80° C., 70 ml of acetonitrile are added to the reaction mixture, which is then cooled further to 0° C. The product that has separated out is filtered off and washed with acetonitrile and diethyl ether. In that manner there is obtained the title compound, m.p. 227°-230° C., 1H-NMR (DMSO): δ=7.57-7.68 (m, 2H); 7.06-7.15 (m, 2H); 7.01 (s, 1H); 5.52 (s, 2H); 5.36 (s, 2H).
