Reaction Steps

A mixture of L-ascorbic acid (0.314 mol; 55.4 g) and p-benzoquinone in 470 ml of ethanol is stirred in darkness under argon for 90 min; then an ethanolic solution (100 ml) of guanidine (0.157 mol) (previously desalified with sodium hydroxide in ethanol) is then added. The medium is stirred at room temperature under argon in darkness for 6 h. The precipitate which forms is filtered, washed with ethanol and dried under vacuum (m=30 g; yield=100%).
