Reaction Steps

This compound was prepared using 148 mg (0.5 mmol) of 2-[(4-iodophenyl)hydrazono]-malononitrile, which was derived from 4-iodoaniline (219 mg, 101.0 mmol) and malononitrile (1.5 mmol) as described in Example 8, and hydrazine hydrate. The hydrazine hydrate was added to the solution at a temperature of 75° C. despite the fact that the starting material had not fully dissolved. The solution cleared briefly and then a precipitate formed. The resulting solid was isolated by filtration, washed with ethanol, and dried to yield 114 mg (70%) of the title compound as a yellow solid.
