YieldReaction ConditionsOperation in experiment
50% With triethylamine; In dichloromethane; at 20℃; for 5h;Inert atmosphere; General procedure: To a solution of a 2-chloro-4,5-dihydroimidazolium chloride in CH2Cl2 was added Et3N followed by a primary amine at r.t. and the mixture was stirred at r.t. After the addition of ice-water and then 20percent aq NaOH solution, the mixture was extracted with toluene. The combined organic solution extracts were washed with H2O and rine to give a guanidine that was purified by column chromatography(silica gel or NH-silica gel) if necessary. An alkyl bromide was added to a solution of the guanidine in MeCN at r.t. and then the mixture was stirred at r.t. After evaporation of the solvent the residue was isolated either as the bromide by successively washing with hexane and Et2O or after purified by column chromatography (silica gel) if necessary as the hexafluorophosphate by treatment with aq NH4PF6 solution at r.t.
