Hydrochloric Acid → [N-(2,6-dimethylphenyl)-N-methylcarbamimidoyl]urea

Participants

Reaction Steps

A mixture of 27 g. (0.106 mole) of 1-(2,6-dimethylphenyl-N-methylamidino)-3-(t-butyl)urea and 200 ml. of conc. hydrochloric acid is refluxed for 178 hour. The reaction mixture is cooled, the precipitated solid filtered and washed with 10 ml. of 1:1 HCl/H2O and dried.
