Vorschrift

50 g of 2-amino-4,6-dichloropyrimidine were suspended in 350 ml of absolute ethanol in a reactor. 181.5 ml of hexylamine (reagent A) were added in a single portion and the mixture was refluxed for 3 h. The medium was evaporated under vacuum. The oil obtained was taken up in 600 ml of water with stirring for 1 h, 30 min. The precipitate was filtered off, washed and dried in a heated desiccator. 43.5 g of the expected compound were thus obtained, for a yield of 62%.
