실험 절차

To 40.5 g. (0.315 mole) of 2,6-dimethylaniline is added 0.4 moles of ethereal HCl and 200 ml. of m-cresol. The mixture is then stirred and heated on a steam bath to drive off the ether and excess hydrogen chloride. To the resultant mixture is then added 17.7 g. (0.315 mole) of methyl cyanamide then heated for 2 hours on a steam bath. The reaction mixture is then cooled, added to 150 ml. of conc. sodium hydroxide solution, cooled and extracted with 2 liters of ether. The ether layer is washed with 2 × 1 liter of water, dried over sodium sulfate, charcoaled and evaporated. The residue is triturated with hexane and the precipitate is filtered off and washed with ether and dried to obtain 1-(2,6-dimethylphenyl)-3-methylguanidine.
