Reaction Steps
Hexyltheobromine (7.5 g) was added to 60 ml of 3N sodium hydroxide, and the mixture was refluxed at elevated temperatures for 6 hours. After the reaction mixture was cooled to ambient temperature, it was extracted with chloroform and the extract was dried and concentrated under reduced pressure to give the residue which in turn was subjected to silica gel column chromatography using a chloroform/ethanol (25:2(v/v)) eluent, thereby yielding 2.6 g (38%) of 5-hexylaminocarbonyl-1-methyl-4-methylaminoimidazole as an oil. A portion of this product was then treated with an ethanolic solution of picric acid to give its picrate.
