A pteridine compound having the formula of 6-(bromomethyl)-2,4-diaminopteridine hydrobromide. 2,4-diamino-6-pteridine-methanol.HBr is reacted with triphenylphosphine dibromide or phosphorus tribromide to form 6-(bromomethyl)-2,4-diaminopteridine hydrobromide. The bromine atom in the molecule can then be replaced with the functional group, N-[4-(methylamino)-benzoyl]-L-glutamic acid in the case of methotrexate and N-(4-aminobenzoyl)-L-glutamic acid in the case of aminopterin.
一种具有化学式6-(溴甲基)-2,4-二氨基喹啉盐酸盐的喹啉化合物。2,4-二氨基-6-喹啉甲醇盐酸盐与三苯基膦二溴化物或三溴化磷反应,形成6-(溴甲基)-2,4-二氨基喹啉盐酸盐。然后,分子中的溴原子可以被甲氨基苯甲酰-L-谷氨酸(甲氨基四氢叶酸)或氨基对氨基苯甲酰-L-谷氨酸(氨基四氢叶酸)等功能基团所取代。
