Reaction Steps

Phenyl guanidine nitrate is prepared from a mixture of 12.8 g (0.1 mole) of aniline, 9.0 g of concentrated nitric acid (equivalent to 0.1 mole of HNO3), 12.6 g of a 50 percent aqueous cyanamide solution (equivalent to 0.15 mole of cyanamide) and 100 ml of ethyl alcohol which is heated under reflux for 20 hours. The reaction mixture is then cooled to 0°C for 5 hours and the precipitated product is collected on a filter. The product is purified by recrystallization from ethyl alcohol. The purified white crystalline solid melts at 125°-7°C. The infrared spectrum was consistent with the assigned structure.
