実験手順
60 ml of 5n HCl were added at room temperature within 45 min to a solution of 49.5 ml (300 mM) of 90% veratrylamine and 20.40 g (307 mM) of 98% sodium cyanate in 500 ml of water. After stirring overnight the crystals were collected: 52.66 g (83.5%) of urea with a melting point of 172-3° C. (sublimation 157° C.).
