Hydrolysis rates of 2-(N,N-diethylamino)-4-aminoquinazoline and 2-(N,N-diethylamino)-4-(N,N-dimethylamino)-quinazoline have been determined to observe the influence of substituents at the 4-amino group upon the hydrolysis. pKa values have been also determined for these compounds and analyzed in conjunction with the Hammett σ constants.
在T 1 Cl 4作为催化剂的存在下,在N 1,N 1-二乙基-N 2-芳基氯羧am与氰胺的反应中,合成了一组2-(N,N-二乙基氨基)-4-氨基喹唑啉衍生物。这样的喹唑啉在较高的HCl水溶液中分解成相应的喹唑酮。2-(N,N-二乙基氨基)-4-氨基喹唑啉和2-(N,N-二乙基氨基)-4-(N,N已经确定了-(二甲基氨基)-喹唑啉以观察4-氨基上的取代基对水解的影响。PK一个值已被还确定了这些化合物和与所述哈米特σ常数结合进行分析。
