Reaction Steps
0.1 g of 1-amino-2-(4-methoxyphenyl)imidazole is dissolved in 10 ml of dichloromethane. The solution is treated portionwise during 8 days with 0.29 g of O-diphenylphosphinylhydroxylamine, evaporated and the residue is suspended in 10 ml of water. The difficulty soluble diphenylphosphinic acid is removed by filtration and the filtrate is placed on a column loaded with Amberlite IRA 400 (chloride), whereupon the column is eluted with water. There is obtained 1,3-diamino-2-(4-methoxyphenyl)imidazolium chloride.
