Participants

Procedure

For example, a solution of 1-(3-bromo-2-hydroxy-5-methyl-phenyl)-3-(4-nitro-phenyl)-propan-1-one 201 (1.48 g, 0.004 mol), EtOH (30 mL), diisopropylethylamine (Hunigs base)(3 mL), and 4-Hydrazino-benzamidine 200 (0.93 g, 0.004 mol) is heated at reflux for 4 hr. (reaction times can vary between 2 h to 18 h). The solution is cooled to ambient temperature, filtered, washed with 6N HCl (2×25 mL), and dried for 12-18 h in a vacuum oven to give a 90% yield of 4-{N′-[1-(3-bromo-2-hydroxy-5-methyl-phenyl)-3-(4-nitro-phenyl)-propylidene]-hydrazino}-benzamidine 202 as an off-white solid (1.78 g, 0.0036 mol).
