Reaction Steps
61.5 ml of 5N HCl was added within 30 minutes to a stirred emulsion of 38.51 ml (300 mM) of 97% piperonylamine and 20.40 g of sodium cyanate in 500 ml of water. After stirring overnight the foamy solid is collected, dried, suspended in 500 ml of ether and collected again: 52.57 g (90.2%) of urea with a melting point of 183-84° C.
