Reaction Steps

0.164 g of 2-amino-4,6-dichloropyrimidine (0.001 mol) and 3 ml of dry DMF, 0.251 g (0.001 mol) of 2-(4-amino-phenylazo)-1,3-dimethyl-3H-imidazol-1-ium chloride and 0.138 g (0.001 mol) of potassium carbonate are charged to a fully equipped round-bottomed flask. The mixture is brought for 17 hours to 80° C. with stirring. After cooling, 4 ml of water are added and the precipitate is filtered off. 100 mg of a red powder containing the starting 2-(4-aminophenylazo)-1,3-dimethyl-3H-imidazol-1-ium chloride and the expected product are obtained. The latter, purified by preparative HPLC, has the following UV absorption characteristics:
