実験手順

A solution of 6-chloro-2,4,5-pyrimidinetriamine (10.94 g, 0.0686 mol) and isoamyl nitrite (9.20 ml, 0.0686 mol)in dioxane (500 ml, freshly purified by passage through basic alumina) was heated under nitrogen with stirring for 2 hours at 90°. The reaction mixture was cooled, treated with activated carbon, filtered, and concentrated to 150 ml. Petroleum ether (250 ml, bp 35-60°) was added. The precipitate was filtered, washed the petroleum ether (50 ml) and dried in vacuo over P2O5 at 40° for 16 hours to give 9.23 g of crude desired product which was then used in the next step.
