Reaction Steps

To Methyl 4-iodobenzoate (30.0 g, 114 mmol) in ethanol (180.0 ml) was added hydrazine hydrate (30.0 g, 599 mmol). The reaction mixture was reflux for 22.5 hours. Heating was stopped and then water (300.0 ml) was added. After cooling down to room temperature, white solid was appeared. The white product solid was collected by filtration. The product was washed with water and dried under vacuum. Final white pure product was obtained in 26.0 g (86.7%). 1H NMR (400 MHz, DMSO-d6, δ): 9.84 (s, 1H, NH), 7.82 (d, J=8.4 Hz, 2H), 7.59 (d, J=8.4 Hz, 2H), 4.50 (s, 2H, NH2).
